On 23 September 2024, Israel began a series of airstrikes in Lebanon as part of the ongoing Israel–Hezbollah conflict with an operation it code-named Northern Arrows. Since then, Israel's attacks have killed over 800 people, injured more than 5,000, and displaced hundreds of thousands of Lebanese civilians. The attacks are the deadliest in Lebanon since the end of the Lebanese Civil War, and began five days after Israel performed a deadly pager and walkie-talkie attack on devices intended for Hezbollah members, and three days after Israel performed an airstrike on an apartment complex in Beirut which killed Redwan Force commander Ibrahim Aqil as well as 54 others.

The deadliest day was 23 September, when Israeli attacks killed 558 people, including 50 children and 94 women. Additionally, Israel hit 14 ambulances and fire engines, killing four emergency responders and wounding 16 other medics. The attacks caused chaos among Lebanese civilians, forming traffic jams as they attempted to flee. Hundreds of schools were converted into shelters, where NGOs and volunteers worked to meet the needs of the displaced, as the Lebanese government struggled to provide adequate support. More than 50,000 people fled from Lebanon to Syria.

A US Department of State official said the US did not see Israel's reported strategy of "escalate to de-escalate" as being effective. Lebanese Prime Minister Najib Mikati called the attacks a "war of extermination" and accused Israel of trying to destroy Lebanese villages and towns. Governments and human rights organizations have called for de-escalation. Israel has rejected these calls and has said it will continue the attacks.

On 27 September 2024, Israel air strikes assassinated Hassan Nasrallah, who was the Secretary-General of Hezbollah. On 1 October, Israel invaded Lebanon.

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" by firing on Israeli military outposts in Shebaa Farms, and 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 approximately 500,000 in Lebanon have been displaced. As of 24 August 2024, there were 564 confirmed deaths in Lebanon, including 133 civilians. 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. Both Israel and Hezbollah have outstanding obligations under UNSCR 1701. Diplomatic efforts, led by U.S. envoy Amos Hochstein and France, have so far been unsuccessful in resolving the conflict. Late on 16 September 2024, the Security Cabinet of Israel established a new Israel-Hamas war objective: the safe return to the north of residents displaced by the cross-border conflict with Lebanon. This goal was added to the two existing objectives: dismantling Hamas and securing the release of hostages taken during the 7 October attacks.

On 17 and 18 September 2024, thousands of handheld pagers and walkie-talkies exploded in a coordinated series of attacks. The explosions killed 42 people and injured at least 3,500, including civilians. Health Minister Firass Abiad said the vast majority of those treated in emergency rooms were in civilian clothing and their Hezbollah affiliation was unclear. Qassim Qassir, a Lebanese expert on Hezbollah, said the attacks mostly struck civilian workers, leaving its military wing largely unaffected. Reuters reported that, according to an unnamed Hezbollah official, 1,500 Hezbollah fighters were taken out of action due to injuries, with many blinded or having lost their hands. Despite Israel denying involvement with the attack, unnamed Israeli sources told Reuters and other media that it was orchestrated by Israel's intelligence service (Mossad) and military. In response, Hezbollah, who described the attack as a possible declaration of war by Israel, launched a rocket attack on northern Israel a few days later. On 20 September 2024, tensions further rose after Ibrahim Aqil was killed in an Israeli strike in Beirut, along with other senior commanders from the unit. After advising Lebanese citizens to evacuate, Israel began airstrikes on 23 September.

The IDF said it had attacked 1,300 Hezbollah military sites in southern Lebanon and the Beqaa Valley. One attack hit as far as Byblos, north of Beirut. The first wave of attacks began at 06:30 EEST and hit hospitals and ambulances according to Firass Abiad, the Lebanese Health Minister. According to the United Nations Office for the Coordination of Humanitarian Affairs (OCHA), 83 civilians were confirmed killed by Israeli attacks, and 93,881 civilians fled their homes. According to the OCHA, Israeli attacks have damaged civilian infrastructure such as water, electricity, and telecommunications installations.
