Israel and the Lebanese militant group Hezbollah have exchanged fire along the Israel–Lebanon border and in the Israeli-occupied Golan Heights since 8 October 2023. Israel has also carried out airstrikes against Hezbollah throughout Lebanon and in Syria. The conflict is part of the spillover of the Israel–Hamas war and is the largest escalation of the Hezbollah–Israel conflict since the 2006 Lebanon War.

On 8 October 2023, Hezbollah started firing guided rockets and artillery shells at Israeli positions in the occupied Shebaa Farms, which it said was in solidarity with Palestinians following the Hamas attack on Israel and beginning of Israeli bombing of the Gaza Strip. Israel retaliated by launching drone strikes and artillery shells at Hezbollah positions near Lebanon's boundary with the Israeli-occupied Golan Heights.

In northern Israel, the ongoing conflict has forced approximately 96,000 individuals to leave their homes, while in Lebanon, over 1.4 million individuals have been displaced, with Hezbollah saying it would not stop attacks against Israel until it stops its attacks and military operations in Gaza. During the conflict, Israel has launched attacks at a much higher rate than Hezbollah has. Between 21 October 2023 and 20 February 2024, the United Nations Interim Force in Lebanon (UNIFIL) recorded an estimated 7,948 incidents of artillery fire from the south of the Blue Line (from Israel to Lebanon) and 978 incidents of artillery fire from the northern side (from Lebanon to Israel).

There was a significant escalation in September 2024, starting with the Lebanon pager explosions, which targeted Hezbollah and were widely attributed to Israel. Forty-two people were killed and thousands wounded. On 23 September, Israel began an aerial bombing campaign throughout Lebanon, codenamed Operation Northern Arrows, which included assassinations of senior Hezbollah commanders. Israel said its attacks would continue until its citizens could return safely to the north. The first day was the deadliest, with Israeli strikes killing at least 558 people and injuring more than 1,800 including children, women and paramedics. On 27 September, the Israeli Air Force bombed and destroyed Hezbollah's main headquarters in Beirut, killing Hezbollah leader Hassan Nasrallah. On 1 October, the Israeli military began an invasion of southern Lebanon, also known as the Third Lebanon War by some Israeli sources, and announced that Israel had been carrying out small covert raids into Lebanon for months. Since then Israel has kept the extent of its campaign vague. On 29 October, IDF officers said that while some Lebanese villages still pose a threat to Israel, most military goals in Lebanon border area were fulfilled and conditions were created to staple Israel's achievements in ceasefire negotiations.

Hezbollah is a Lebanese Shiite political party and paramilitary group, formed in 1982 by Muslim clerics with Iranian funding to fight the Israeli invasion of Lebanon. After the war, Israel continued to hold borderland buffer zone in southern Lebanon with the aid of proxy militants in the South Lebanon Army (SLA). In 2000, Israel withdrew from South Lebanon to the UN-designated and internationally recognized Blue Line border. Hezbollah quickly took control of the area. It has justified its continued existence, occupation, and attacks on Israel by citing both allegations of Lebanese prisoners in Israel and continued Israeli control of the Shebaa farms region, occupied by Israel from Syria in 1967 but considered by Hezbollah to be part of Lebanon.

Elimination of the state of Israel has been a primary goal for Hezbollah from its inception. Hezbollah opposes the government and policies of the State of Israel.

Since the 1948 Palestinian expulsion and flight, Palestinian refugees have had a presence in southern Lebanon as numerous refugee camps were established, which brought many Palestinian factions into south Lebanon, with it being often used as a center to launch rockets into northern Israel. The Palestine Liberation Organization was based in Lebanon after being expelled from Jordan by King Hussein in July 1971. After they were involved in an insurgency in Southern Lebanon, until they were expelled to Tunis after the 1982 Lebanon War.

A ceasefire was reached between Israel and Hezbollah at the end of the 2006 Lebanon War, based on the terms of UN Security Council Resolution 1701 which called for a demilitarized zone between the southern border of Lebanon and the Litani river. The UN Security Council resolution mandated only the Lebanese army and United Nations Interim Force in Lebanon (UNIFIL) could be armed in southern Lebanon. It also stated that neither side should cross the Blue Line, which marks the border between Lebanon and the Golan Heights, and divides the village of Ghajar between the two. Despite this, both Israel and Hezbollah have outstanding obligations under UNSCR 1701.

Since 2006, Hezbollah fortified southern Lebanon, obstructed UNIFIL's access, built tunnels into Israel, and crossed the Blue Line. Israel has also accused Hezbollah of using a local environmental organization as a front for its military activities near the Blue Line. After retreating behind the Blue Line in 2000, Israel reoccupied the whole of Ghajar in 2006, including the Lebanese part of the village. Israel continues to occupy Ghajar and an adjacent area, and has repeatedly breached Lebanese airspace, waters, and borders. UNIFIL reports that Israel entered Lebanese airspace on more than 22,000 occasions between 2007–2021.

On 6 April 2023, in response to the 2023 Al-Aqsa clashes, dozens of rockets were fired from Lebanon into Israel, injuring three Israeli civilians. The Israel Defense Forces said that it intercepted 25 rockets fired from Lebanon, which it said were fired by Palestinian factions Hamas and PIJ with Hezbollah's approval.

The attacks were the largest escalation between the two countries since the 2006 Lebanon War. The United Nations Interim Force in Lebanon (UNIFIL) described the situation as "extremely serious" and urged restraint.

On 15 July, the IDF fired warning shots and used riot dispersal munitions on 18 people, including journalists and parliamentarians that crossed the border from Lebanon and walked 80 meters into Israeli-occupied territory.

On 8 October 2023, a day after Hamas launched its 7 October 2023 attacks on Israel and Israel began its bombing of Gaza, Hezbollah joined the conflict in "solidarity with the Palestinians", initially firing on Israeli military outposts in Shebaa Farms and the Golan Heights — both territories under Israeli occupation. Since then, Hezbollah and Israel have been involved in cross-border military exchanges that have displaced entire communities in Israel and Lebanon, with significant damage to buildings and land along the border. From 7 October 2023 to 20 September 2024, there were 10,200 cross border attacks, of which Israel launched 8,300. Over 96,000 people in Israel and over 111,000 in Lebanon have been displaced during this period. Israel and Hezbollah have maintained their attacks at a level that causes harm without escalating into a full-scale war.

Hezbollah has stated it will continue attacking Israel until Israel halts its operations in Gaza, where over 40,000 Palestinians have been killed. Israel demanded that Hezbollah implement UNSC 1701 and withdraw its forces north of the Litani River. Diplomatic efforts, led by U.S. envoy Amos Hochstein and France, have so far been unsuccessful in resolving the conflict.

In November 2023, Israeli defense minister Yoav Gallant warned that Beirut could meet the same fate as Gaza. He made the same warning in January 2024. In June 2024, Gallant visited the United States, seeking support for an escalation of the war with Hezbollah and a possible ground invasion in Lebanon.

In the morning of 8 October, Hezbollah fired rockets and shells at the Shebaa Farms region in support of Hamas' attack onto Israel; in response, the Israel Defense Forces (IDF) fired artillery shells and a drone into southern Lebanon. Two Lebanese children were reportedly injured by broken glass.

The next day, Israel exchanged a series of airstrikes on southern Lebanon near the towns of Marwahin, Ayta ash Shab and Dhayra in the Bint Jbeil district. This was after numerous Palestinian militants infiltrated the Israeli border, which Hezbollah denied involvement with. The Palestinian Islamic Jihad militia claimed responsibility for the armed infiltration. The IDF killed at least two perpetrators (likely Palestinians), while a third returned to Lebanon. A Hezbollah media source announced three of Hezbollah's members died in the IDF retaliation. Hezbollah fired rockets and artillery in retaliation. During the clashes, two Israeli soldiers and Lt. Col Alim Abdallah, Deputy Commander of the IDF's 300th Brigade, were killed and another three were wounded.

On 11 October, Hezbollah fired anti-tank missiles at an IDF position and claimed to have produced casualties. In response, the IDF shelled the area where the attack was launched. The Lebanese-Italian hospital in Tyre admitted three injured civilians. The IDF ordered residents of northern Israel to seek shelter following reports of drones being launched from southern Lebanon. A Patriot missile was launched to intercept a suspicious projectile, after which the IDF found that the object in question was not a drone. Warning sirens were activated across northern Israel after reports emerged that up to 20 infiltrators on paragliders had entered Israeli territory from Lebanon before the IDF dismissed the report as a false alarm.

Hezbollah deputy chief Sheikh Naim Qassem said "when time comes for any action, we will carry it out," stating that Hezbollah was ready and would contribute to confrontations against Israel according to its own plan. The IDF fired artillery, into southern Lebanon following an explosion that caused minor damage to a section of the Israel–Lebanon border wall near the kibbutz of Hanita.

The IDF released footage of a drone attack which, according to them, killed three infiltrators from Lebanon near Margaliot who were members of Hamas. One of them was acknowledged by Hezbollah as one of their members. In the afternoon, Hezbollah fired 50 mortar shells and six anti-tank missiles towards five Israeli outposts in the Shebaa Farms. Further IDF shelling killed two civilians in a Shebaa village; video and photographic evidence showed usage of phosphorus bombs.

On 15 October, Hezbollah launched five anti-tank missiles towards northern Israel killing one civilian and injuring three others in Shtula. UNIFIL said that their headquarters in Naqoura in southern Lebanon was hit by rocket fire with no casualties reported. Lieutenant Amitai Granot, commander of the 75th Battalion of the IDF's Golan Brigade and son of Rabbi Tamir Granot, was killed in a missile attack on an IDF post bordering Lebanon.

On 13 October, while a group of Reuters, AFP and Al Jazeera journalists were transmitting a live video feed of an IDF outpost in Aalma ech Chaab, two tank rounds fired directly hit the group. The first killed Reuters photojournalist Issam Abdallah. The second strike was much more powerful and ignited the Al Jazeera vehicle, a white Toyota, which Al Jazeera journalists Carmen Joukhadar and Elie Brakhya, as well as their AFP colleague Dylan Collins were standing next to. Reuters photographer Christina Assi was also critically injured. The Lebanese Army has said the IDF fired the missile that killed Abdallah. Another Reuters reporter at the scene said Abdallah was killed by projectiles fired from the direction of Israel. His last post on Instagram, posted a week before he was killed, was a photograph of Shireen Abu Akleh, a Palestinian journalist for Al Jazeera Arabic who had been killed by Israel in 2022.

A February 2024 report by the United Nations Interim Force in Lebanon concluded that an Israeli tank killed Abdallah when it fired at "clearly identifiable journalists", and that this broke international law. The report "assessed that there was no exchange of fire across the Blue Line at the time of the incident", with no records of any exchange of fire across the border for the 40 minutes before the tank firing. The IDF responded to the report by claiming that Hezbollah attacked them, prompting them to retaliate with tank fire.

On 16 October, Amnesty International reported that the IDF fired white phosphorus shells into Dhayra, hospitalizing nine civilians and setting fire to civilian objects. Aya Majzoub, Amnesty International's Deputy Regional Director for the Middle East and North Africa, described the attack as a violation of international law that needed to be investigated as a war crime, and that it "seriously endangered the lives of civilians, many of whom were hospitalized and displaced, and whose homes and cars caught fire".

Lebanese state media reported that Dhayra and other areas along the western section of the border came under "continuous" bombardment overnight. In the early morning it was reported that multiple people were suffering from symptoms of suffocation after the IDF allegedly fired white phosphorus shells on the village. Three people were injured after an anti-tank missile from Lebanon landed in the Israeli town of Metula. Hezbollah announced that five of its members were killed on the same day but it was unclear if any had involvement in the border infiltration.

On 19 October, the Lebanese Armed Forces said that one person was killed and another injured after a group of seven Iranian journalists were targeted with machine guns by Israel, although Iranian state media denied the claim and said that all its journalists were "alive and healthy". UNIFIL peacekeepers said that one person was killed after civilians were caught in a cross-fire at the border in which the Lebanese Army requested assistance by UNIFIL to deescalate the situation. It was requested to Israel to suspend fire "to facilitate the rescue operation".

Israel started evacuating the settlements located close to the border with Lebanon in October 2023 with more than 60 thousand evacuated by April 2024.

In the early afternoon of 21 October, several rockets were fired from Lebanon toward the Shebaa Farms; there were no injuries. The IDF conducted a drone strike on the team of militants that launched the rockets. A short while later, anti-tank guided missiles were fired from Lebanon toward Margaliot and Hanita; two foreign workers were injured. The IDF conducted airstrikes against the missile teams. In the evening, another anti-tank guided missile was fired from Lebanon toward Bar'am. One IDF soldier was seriously injured and two others suffered minor injuries.

In response, Hezbollah fired at Kiryat Shmona, killing an Israeli civilian.

The Al-Qassam Brigades took responsibility for firing 16 rockets from Lebanon targeting areas south of Haifa. Meanwhile, Israel reported at least 30 rockets being fired in which the IDF fired back at the sources. Hezbollah and Al-Qassam brigades also conducted four cross-border attacks into northern Israel. Hezbollah deputy general Naim Qassem said that the group could be forced into wider conflict over Israeli attacks in Gaza.

According to Tel Aviv University economist Tomer Fadlon, there would be long-term and significant effects on northern Israel's economy if its population did not return. He further said that even if Israel achieved victory in Gaza, the north would possibly not see an economic recovery. The conflict severely hurt the tourism industry in the north, which employs many people. Many factories in the region have not shut down but suffered labor shortages of up to 50%. According to an estimate by the Bank of Israel in November 2023, the Israeli economy suffers the loss of 590 million shekels ($158 million) every week due absence of work caused by the evacuation of 144,000 people after the Israel–Hamas war, 40% of them from the north.

Once-robust communities such as Snir and Kiryat Shmona were mostly emptied following the evacuation orders in northern Israel. Kiryat Shmona was planned to be used by food technology businesses, but companies left following the city's evacuation in October 2023. Northern Israel has one-third of Israel's agricultural land, and the occupied Golan Heights and Galilee accounted for 73% of Israel's annual egg production; however, after the outbreak of the conflict, few people remained in the north to tend chicken coops, resulting in a decline in domestic egg production. In August 2024 the Ministry of Agriculture and Food Security approved a quota for the import of 45 million eggs due to the anticipated drop in local production over the conflict and other reasons.

In October 2024, Israel bombed financial institutions it stated were affiliated with Hezbollah, leading Amnesty International to state the strikes should be investigated as possible war crimes.

On October 2024, Israel attacked the UNIFIL peacekeeping bases in southern Lebanon. In response, UNIFL stated, "Any deliberate attack on peacekeepers is a grave violation of international humanitarian law and of Security Council resolution 1701". According to the Israeli Ambassador to the UN, "Hezbollah terrorists are using UNIFIL outposts as hiding places and as places of ambushes."

On 5 November 2023, an Israeli airstrike hit a car near Ainata, Lebanon, killing three children and their grandmother, and injuring their mother. The IDF admitted to striking the vehicle. Human Rights Watch stated that their killings should be investigated as an apparent war crime.

In September 2024, thousands of wireless communication devices exploded throughout Lebanon and Syria in an attack attributed to Israel, killing dozens of people, including civilians and Hezbollah militants. Lama Fakih, a director of the Human Rights Watch, said that the explosions would constitute an indiscriminate attack if the IDF had no way of accurately determining the location of the explosive devices since there would be no distinction between civilians and military targets. UN High Commissioner for Human Rights Volker Türk said that the attacks violated international human rights since the IDF did not have knowledge regarding the users of the devices or their location and surroundings during the explosions.

According to the Syrian Observatory for Human rights, 232 Syrian refugees were killed by the IDF in Lebanon since the start of the Israel-Hamas war.

According to the Council of Europe, the intentional targeting of journalists constitutes a war crime. During the conflict, Reporters Without Borders (RSF) claimed that the Israeli army had deliberately targeted journalists. An RSF investigation said that Israel had targeted journalists in two missile strikes on 13 October 2023 that killed Reuters reporter Issam Abdallah and injured four others. These two strikes, 30 seconds apart, hit a group of seven journalists in southern Lebanon who were reporting on the border fighting between Israel and Hezbollah. In a video, the journalists are seen wearing vests and helmets identifying them as "PRESS". The marking was also present on the roof of their car, which exploded after being hit by the second missile. The Netherlands Organisation for Applied Scientific Research, which tests and analyses munitions and weapons, assisted Reuters by examining the material collected at the site of the explosion and found that a piece of metal was the fin of a 120 mm tank round fired 1.34 km away from the border from a smoothbore tank gun.

On 26 December 2023, a Hezbollah anti-tank missile impacted near a Channel 13 News team while they were interviewing a farmer at Dovev for an article following a prior Hezbollah assault that killed a 56-year-old employee of the Israel Electric Corporation, and injured five workers who were repairing electric lines.

On 31 October 2023, after an investigation, Amnesty International stated that an Israeli white phosphorus attack on 16 October was indiscriminate, unlawful, and "must be investigated as a war crime", due to its use on the populated Lebanese town of Dhayra, which injured at least nine civilians. On 2 November, Amnesty International stated its investigations into four incidents on 10, 11, 16 and 17 October showed Israel had used white phosphorus munitions. The claim was confirmed by the Washington Post, which identified two white phosphorus shell casings made in the U.S. Human Rights Watch verified IDF's use of white phosphorus in at least 17 municipalities in Lebanon, including five municipalities where airburst munitions were used over residential areas. It also called on the Lebanese government to file a declaration to enable investigations in the International Criminal Court.

In southern Lebanon, Israel's white phosphorus bombs have destroyed over 4,500 hectares (45,000,000 m) of forest with economic loses being valued at US$20 million. The American University of Beirut estimated use of white phosphorus has led to more than 134 forest fires as of June 2024 burning 1,500 hectares (15,000,000 m) of land. As of 28 May 2024, the Lebanese Ministry of Public Health said that exposure to white phosphorus had injured at least 173 people.

The targeting of hospitals, as well as religious sites, constitutes a war crime. Lebanese health minister Firass Abiad said that 163 rescuers and health workers were killed and 273 others were injured in Lebanon since the start of Israel-Hezbollah conflict. Human Rights Watch stated that Israel's "repeated" attacks on medical workers and healthcare facilities were apparent war crimes.

The IDF shelled Meiss Ej Jabal Hospital, injuring a doctor on 10 November 2023. The missiles did not explode but caused damage to the emergency department and several cars.

Days before, four people were reportedly injured after an Israeli bombing that hit two ambulances. The Lebanese National News Agency said that an Israeli drone strike hit two ambulances belonging to the Risala Scout Association, which is affiliated with the Amal Movement.

On 26 December 2023, an anti-tank missile shot by Hezbollah fighters from Lebanon damaged a shed in a church compound in Iqrit, but not the church itself, wounding an elderly civilian.

On 7 May 2024, Human Rights Watch declared the 27 March incident as an unlawful attack on civilians and said that they did not find any evidence of military targets at the site that was targeted. Investigations also showed that the IDF used an MPR 500 missile to conduct the raid.

On 27 May 2024, an Israeli airstrike near Salah Ghandour Hospital in Bint Jbeil killed three civilians. WHO in Lebanon condemned the attack and called for the protection of hospitals and healthcare workers. In October 2024, the head of Lebanon's Civil Defence in the south said Israel was specifically attacking health workers, stating, "We have had 40 ambulances which have been completely destroyed. On top of that 24 rescuing stations have been hit - just in this area." Lebanese health officials stated on 5 October 2024 that fifty health officials had been killed in the prior 72 hours. Lebanon's health minister Firas Abiad stated the attacks were war crimes and part of Israel's systematic targeting of Lebanon's healthcare system. A November 2024 investigation found Israel had struck in "lethal proximity" to nineteen different hospitals in Lebanon.

Experts warned the 2024 Lebanon pager explosions potentially violated international humanitarian law. Josep Borrell, the European Union's High Representative for Foreign Affairs and Security Policy, questioned the legality of the pager attacks due to their high collateral damage among civilians, including the deaths of children. Jeanine Hennis-Plasschaert, the United Nations Special Coordinator for Lebanon, also raised concerns that the attacks were illegal. Belgian deputy prime minister Petra De Sutter went further, calling it a "terror attack." Volker Turk, the UN human rights chief, stated, "International humanitarian law prohibits the use of booby-trap devices in the form of apparently harmless portable objects".

Booby traps are mostly outlawed under the Protocol on Mines, Booby-Traps and Other Devices ("Amended Protocol II") of the Convention on Certain Conventional Weapons, to which Israel is a party. Article 7, paragraph 2 of Amended Protocol II prohibits the use of "booby-traps or other devices in the form of apparently harmless portable objects which are specifically designed and constructed to contain explosive material." The rules of engagement of some countries, such as the United Kingdom, also ban explosive devices disguised as harmless items. The United States Department of Defense Law of War Manual gives watches, cameras, tobacco pipes, and headphones as examples of such items, which are prohibited to "prevent the production of large quantities of dangerous objects that can be scattered around and are likely to be attractive to civilians, especially children".

On 22 September 2024, Israeli President Isaac Herzog denied any Israeli involvement in the explosions.

The elimination of the State of Israel has been a primary goal for Hezbollah. Hezbollah has been accused of "only [regarding] the Jews living in Israel as Zionists, who should be killed". Throughout the war Hezbollah announces the targeting of civilian homes. On 12 November 2023, Hezbollah fired an anti-tank missile killing an employee of the Israel Electric Corporation who was conducting repair work and injured 13 other Israelis, including six other employees of the Israeli Electric Corporation.

The most notable of Hezbollah's attacks on civilians was on 27 July 2024 in the Majdal Shams attack, when Hezbollah fired an Iranian-made Falaq-1 rocket at Majdal Shams, a Druze town in the Golan Heights. The rocket hit a football pitch killing 12 Druze children and injuring at least 42 others.

Another attack by Hezbollah resulted in civilian casualties on 9 July 2024, when a rocket struck a couple's car just south of their hometown of Ortal. Additionally, a couple walking their dog in Kiryat Shmona was killed by shrapnel from a Hezbollah rocket on 9 October 2024.

There have been claims that Hezbollah has intentionally drawn fire to Christian areas in southern Lebanon. Christians in the town of Rmaich clashed with Hezbollah due to the organization's attempts to establish military infrastructure in the town. The residents also wrote a complaint letter. On 26 March 2024, civilians in Rmaich confronted militants and rang their church bells after Hezbollah attempted to place rocket launchers in the town. Hezbollah denied trying to fire rockets from Rmaich.

On 16 October 20 rocket launchers were discovered by the Lebanese Army in the towns of Al-Qlaileh and Chaaitiyeh which have been suspected to be a part of Hezbollah infrastructure. Four reportedly had rockets inside of them and were ready to be fired. They were immediately dismantled by the Lebanese Army.

The Lebanese Kataeb Party criticized Hezbollah for allegedly storing weapons between houses stating that "Hiding weapons between houses does not support Gaza" after an IDF strike on Hezbollah infrastructure in Adloun. Rockets were still exploding about an hour after the strike was reported and the blasts lightly injured three citizens as shrapnel from the explosions flew to surrounding villages. These ammunition depots "open the door to Israeli attacks and turn the Lebanese into human shields", the Kataeb party said.

According to IDF's Arabic spokesman, Avichay Adraee, Hezbollah-run yellow ambulances have been used to transport fighters and weapons. The Islamic Health Authority's website says it has "provided services for the activity of the Hezbollah fighters against the Zionist occupation." According to UNIFIL, Hezbollah has used the environmental NGO "Green Without Borders" to provide direct cover for Hezbollah's military operations by "unlawful construction of military outposts along the Blue Line." Hezbollah has also launched rockets form UNIFL positions. The IDF reported that 25 rockets were launched from UNIFL positions in October 2024 and said that it discovered hundreds of weapons, including firearms, grenades, and rocket launchers, stored in compounds located near UNIFIL posts in southern Lebanon.

After the 20 September 2024 Beirut attack which killed major Redwan Force commanders in the densely populated Dahieh suburbs, Daniel Hagari said that the commanders were holding a meeting "gathered underground under a residential building in the heart of the Dahieh neighbourhood, hiding among Lebanese civilians, using them as human shields."

On 23 September 2024, the IDF began posting pictures and videos of what it claimed was evidence of Hezbollah placing weapons in people’s homes. They also released video footage of secondary explosions after targeting buildings which it says are from Hezbollah munitions stored in residential areas.

On 6 November 2023, in response to the killing of four civilians in southern Lebanon, Prime Minister Najib Mikati announced that his government would submit an urgent complaint to the UN Security Council against Israel saying that its "targeting of civilians in its aggression against Lebanon" was a "heinous crime".

Samir Geagea, the leader of a main Christian political party, blamed Hezbollah for attacking Israel and said that it harmed Lebanon while having no impact on Israel's Gaza offensive.

As tensions heightened on 8 October 2023 near the Lebanese border, former prime minister Fouad Siniora stressed that Lebanon should not be involved "in any hostilities with the Israeli enemy".

Between 7–9 October 2023, many politicians of long-established Christian parties in Lebanon took a stance against Hezbollah's involvement as well. Pierre Bou Assi, a member of the Lebanese Forces' Strong Republic bloc highlighted the kidnapping of two IDF soldiers which led to the 2006 Lebanon war saying, "Hassan Nasrallah promised, in early July, that the summer would be quiet and thriving—but a few days later, Hezbollah kidnapped two Israeli soldiers and the July war broke out". The Kataeb Party took a similar stance and condemned the use of Lebanese territory by non-state actors for launching attacks on Israel.

On 4 December 2023, Hamas announced the organization's official establishment in Lebanon. The Lebanon-based unit was named the “al-Aqsa Flood Vanguards unit”. The establishment of the Vanguards during the 2023 Hamas-led attack on Israel faced severe criticism from various political figures and factions within Lebanon. Many argued that such an organization, with potential military implications, could infringe upon Lebanon's sovereignty and violate international resolutions, particularly the Taif Agreement. Critics, including members of the Christian Lebanese Forces Party and other political figures, voiced concerns about a potential recurrence of historical issues related to armed Palestinian factions operating from Lebanese territory.

Screens at Beirut–Rafic Hariri International Airport were hacked allegedly by the Christian group Jnud al-Rab to display an anti-Hezbollah message. Jnud al-Rab denied any involvement.

On 28 January 2024, Bechara Boutros al-Rahi, Maronite Patriarch and head of the Maronite Church, stated that residents of southern Lebanon refuse to be used as "sacrificial lambs" in what he described as a "culture of death", implicitly referencing Hezbollah's border activities. He described the hardships faced by the people, including psychological strain and disrupted education for children, and said they refuse to be hostages or human shields.

On 24 March 2024, a video showed a nun at a Lebanese Christian school asking students to pray for Hezbollah men defending Lebanon. The video went viral, with some praising the video and others criticizing it.

On 9 January 2024, the Kata'ib Hezbollah spokesperson Jafar al-Husseini warned that the Islamic Resistance in Iraq would help Hezbollah fight Israel if war erupted between the two sides. This statement was a few weeks after the Islamic Resistance in Iraq claimed responsibility for a drone attack on a Karish rig which Lebanon claims to hold sovereignty to. On 23 June 2024, the spokesperson to Kata'ib Sayyid al-Shuhada Kadhem al-Fartousi said the brigade will join Hezbollah's side if Israel decides to launch a full-blown war in Lebanon.

On 24 June 2024, Qais al-Khazali, the leader of Asa'ib Ahl al-Haq, stated in a televised speech that if the US continued to support Israel in expanding the war to Lebanon and Hezbollah, the group would begin to attack US interests in Iraq and the Middle East.

On 4 November 2023, United States Secretary of State Antony Blinken thanked prime minister Najib Mikati during a meeting in Amman "in preventing Lebanon from being pulled into a war that the Lebanese people do not want". United States Secretary of Defense Lloyd Austin expressed concern about Israel's role in ongoing tensions with Lebanon.

On 30 September 2024, the Pentagon said it would be deploying a "few thousand" more troops to the Middle East. On 1 October 2024, Defense Secretary Lloyd Austin told Israeli defense minister Yoav Gallant that the United States supports Israel′s ground offensive against Hezbollah in southern Lebanon.

The U.S. Embassy in Beirut announced on 27 September 2024 that it was "not evacuating U.S. citizens at this time." In response, U.S. Representative Rashida Tlaib stated, the State Department was "leaving Americans behind and failing to protect their own citizens". American citizens in Lebanon stated they were being treated like "lesser US citizens". Lebanese Americans filed a class-action lawsuit against the State Department in the hopes of expediting an evacuation.

French Armed Forces Minister Sébastien Lecornu announced that France would donate dozens of armoured vehicles to the Lebanese military to help it carry out patrol missions.

Since June 2024, the foreign ministries of Canada, Kuwait, Germany, the Netherlands and North Macedonia issued statements urging their citizens to leave Lebanon due to fears of an escalation of the conflict. The Canadian Armed Forces said that it was planning to evacuate its 20,000 citizens from Lebanon in the event of an escalation, although it would require support from its allies.

On 8 November 2023, two men were arrested by Brazilian police in São Paulo following a warning from Mossad that Hezbollah was planning an attack against the country's Jewish community. Searches were also conducted in Brasilia and Minas Gerais in connection with the alleged plot.
