On 8 June 2024, during an operation to rescue hostages held in the Nuseirat refugee camp, the Israeli military killed at least 276 people and injured over 698, according to the Gaza Health Ministry and Palestinian health officials. The operation's objective was to recover hostages taken during the 7 October Hamas-led attack on Israel. The Israeli military acknowledged fewer than 100 Palestinian deaths.

Four Israeli captives were rescued—Noa Argamani, Shlomi Ziv, Almog Meir Jan, and Andrey Kozlov—from two multi-story residential apartment buildings in Nuseirat. According to the Israel Defence Force, they were held by Gazan civilians affiliated with Hamas and were guarded by armed Hamas militants.

During the operation, the Israeli military called in an intense air, sea, and ground attack. This resulted in civilian casualties. Ziad, a paramedic and resident of Nuseirat and Abu Ubaida, a spokesperson for al-Qassam Brigades referred to the attack as a massacre. EU foreign policy chief Josep Borrell described the events as a "bloodbath." The Gaza Health Ministry reported that at least 274 Palestinians were killed in the camp, including 64 children and 57 women, with at least 698 people reported injured. The IDF said they were aware of fewer than 100 Palestinian casualties. Yamam officer Arnon Zamora was seriously injured and later died from his injuries.

Following the operation, Qassam Brigades spokesman Abu Obaida warned that it would result in greater threats to the Israeli hostages. The Qassam Brigades later released a short video saying that the raid had also killed three unnamed Israeli hostages, including one with dual citizenship of the USA. No evidence for this claim was provided. The UN human rights office said that both Israeli forces and Palestinian armed groups may have committed war crimes. The U.S. had promised aid groups the pier would be a no-go area for Israeli forces and aid operations at the pier are on hold pending a response to aid groups from the U.S. government.

On 7 October 2023, the Qassam Brigades (the militant wing of the Hamas party) launched an attack on Israel. As part of the attack, in which other Palestinian militant groups were also involved, Hamas, Palestinian Islamic Jihad and other Palestinian militant groups kidnapped 251 Israeli civilians and soldiers. This attack led to the Israel–Hamas war.

The Nuseirat refugee camp is a long-standing UNRWA refugee camp located in the middle of the Gaza Strip, in Deir al-Balah. The camp has been repeatedly bombed during the Israel-Hamas war, with over a hundred Palestinians killed in the attacks. The most recent attack on the camp occurred only days before the rescue operation, with IDF forces striking the UNRWA school in the camp, killing at least 33 people. The deceased classification are contested with Gaza sources reporting a number of women and children were in the death toll, while the IDF said the deceased included Hamas Nukhba and Palestinian Islamic Jihad militants.

This operation was the third known successful hostage rescue carried out by the IDF since the start of the war. IDF Corporal Ori Megidish was rescued in October 2023 from the northern part of the Gaza Strip, and two male hostages were rescued in February 2024 from southern Rafah. Additionally, a number of Israeli hostages and Palestinian prisoners were exchanged in 2023.

All four hostages rescued had been abducted from the Re'im music festival, and were identified as Noa Argamani (26-years-old), Almog Meir Jan (22-years-old), Andrey Kozlov (27-years-old), and Shlomi Ziv (41-years-old). Both Argamani and Meir Jan were festival goers while Kozlov, a recent immigrant from Russia, and Ziv had been employed as security guards for the festival.

Argamani was shown in one of the initial videos released by Hamas documenting the massacre. She was seen being taken away on a motorcycle while yelling, "Don't kill me!" Her arms are outstretched towards her boyfriend, Avinatan Or, who was also being kidnapped. This footage became emblematic of the hostage crisis, leading to Argamani being described as "the face of the Nova music festival hostages." Argamani's family had indications that she was alive, as she appeared in a Hamas video released in January 2024.

The abductees had suffered from malnutrition in captivity and were often beaten. The three male hostages, Shlomi Ziv, Almog Meir Jan, and Andrey Kozlov reported that they had gone through physical and psychological abuse while in Hamas captivity in Gaza, as reported by The Wall Street Journal. For six months they were confined to a single dark room without any contact with the outside world. They faced severe punishments for non-compliance, such as being locked in a small bathroom or buried under blankets in intense heat. The doctor in charge of treatment for the rescued hostages said they were beaten and showed signs of malnutrition due to a lack of adequate food while in captivity. Additionally, the captors subjected them to psychological torment, including threats of death and claims that no one was coming to rescue them. Prof. Itai Pesach at the Sheba Medical Centre who treated the three male hostages, stated that they suffered from severe trauma and had muscle atrophy due to malnutrition. The entire Gaza Strip has faced severe food shortages since 9 October 2023, which were ongoing at the time of the raid.

Argamani said she had been held in four different apartments during her eight months in captivity and that in the last location, the family made her wash their dishes. Ynet reported that she also cooked at times with basic ingredients she was provided.

The Qassam Brigades (the militant wing of the Hamas movement) claimed that three other hostages were killed as a result of the raid. They did not name any of them, or show photographs, but they claimed that one of the three was a US citizen and released a short video with text in Arabic, Hebrew, and English. The video depicted three unidentifiable corpses with their faces obscured by censor bars. The Brigades did not give details of how the hostages supposedly died, but said they were killed by the Israeli military.

"In exchange for them, your own army killed 3 of your own captives in the same attack; one of them holds a USA citizenship" - Qassam Brigades, 9 June 2024.

The IDF said that they worked with Shin Bet and Israeli police to free the four Israeli hostages. It was also later reported that the operation was aided by intelligence support from the United States and the United Kingdom. The operation was planned for several weeks, and was carried out after an intelligence opportunity arose. Some of the special forces members entered the refugee camp in a vehicle with a mattress on top, posing as Palestinian refugees fleeing Rafah per Saudi reporters. They reportedly told locals that they were escaping the Israeli assault on Rafah, while other Palestinian locals alleged that other forces entered in humanitarian trucks. However, a senior official in the Biden administration claims that the Israeli forces did not use an aid truck.

The operation began at about 11 a.m., with the Yamam and Shin Bet officers raiding two multi-story buildings about 200 meters apart, in the center of Nusseirat, where the hostages were reportedly held in two family homes. During captivity the hostages were held in a civilian environment, guarded by armed militants. The female hostage, Argamani, was reportedly held separately from the three male hostages, who had been reportedly held together throughout their eight-month captivity. None of them were held in the Hamas tunnel network.

The IDF stated that, at the time of the rescue, the three male hostages were being held in the family home of Ahmed Al-Jamal, a physician. His son Abdullah Al-Jamal, a freelance journalist, was also in the household. Al Jazeera disputed IDF allegations that Abdullah Al-Jamal had been one of its journalists, stating that he had contributed to an opinion piece published on its website but had no other involvement with the network. Abdullah Al-Jamal had also contributed to the Palestine Chronicle, a nonprofit online publication based in the United States. Ramy Abdu, chairman of the Euro-Mediterranean Human Rights Monitor, reported that Ahmed Al-Jamal, Abdullah Al-Jamal, and the latter's wife were all killed after Israeli forces stormed the home by ladder. The Palestine Chronicle claimed inconsistencies in the Israeli narrative, but a Wall Street Journal investigation found that the Al-Jamal family had been known for its close ties with and support of Hamas. Locals criticized Hamas for placing hostages in civilian areas.

During the extraction of the three male hostages, a major gun battle reportedly erupted, causing the critical wounding of the commander of the Yaman rescue team for that building. During the operation, the Southern Command and the Air Force said they exchanged fire with Hamas militants. An IDF spokesman said its forces were fired upon inside buildings and during their withdrawal from Gaza. The three male hostages were extracted from the refugee camp, but when the extraction vehicle became stuck, additional forces had to rescue them as the vehicle came under fire. They were then brought to a landing zone on the coast and airlifted into Israel. The abductees were not injured, and were transferred to Sheba Medical Center.

A witness in the camp reported a "crazy bombardment" occurred suddenly, while another stated that the strike happened when people were sleeping. Witnesses reported that entire residential blocks were wiped out. A witness who had been in the marketplace stated that about 150 rockets fell at and around the market place in less than 10 minutes. Per a resident and paramedic in the camp, the assault felt like a "horror movie" and that Israeli drones and warplanes fired randomly throughout the night at peoples homes and those who tried to flee the area. Videos were posted to social media, reportedly showing corpses with entrails spilling out lying on blood-stained streets after the attack, although Reuters was unable to immediately verify the footage. Additional footage showed Palestinians in the market area diving for cover as missiles flew in and gunfire erupted.

The US denied that its Gaza floating pier (intended for the delivery of aid into Gaza) was used in the operation. The denial followed the release of imagery showing the landing zone used for the air evacuation immediately south along the coast from the pier, with the U.S. facility clearly visible in the near background.

According to reports, "at least one of the vehicles" containing the three male captives broke down and the Israeli military called in support, "attacking from the air, from the sea and on the ground with massive force."

At 11:27 a.m., a strike occurred near the building from which the three male hostages were rescued. Subsequently, the building was demolished by another strike. Shortly before noon, another strike demolished the building where Noa Argamani had been held captive. Eyal Shahtout, a resident of a neighboring building, informed The New York Times that his home was hit, resulting in many of his family members being buried under the debris. 18 of his family members were killed, including his wife, four children, and two grandchildren. The Israeli military did not provide an explanation for why the home was targeted. To the south of the hostage sites, a market was also struck. At 11:45 a.m., plumes of smoke were visible in downtown Nuseirat.

Scores of local people, including children, were killed. According to a statement from Doctors without Borders, which works nearby at the Al-Aqsa Martyrs Hospital in Deir al-Balah, "there have been back-to-back mass casualties as densely populated areas are bombed. It’s way beyond what anyone could deal with in a functional hospital, let alone with the scarce resources we have here." The Al-Awda Hospital in Nuseirat was also overwhelmed with casualties, "including many children laid out in the corridors". The strikes destroyed "apartment buildings throughout" [the] "camp, according to witnesses and video footage". The UN human rights office said that both Israeli forces and Palestinian armed groups may have committed war crimes, citing potential "violations of rules of proportionality, distinction and precaution" in the case of the former and "holding hostages in densely populated areas" for the latter.

The death toll resulting from the operation has been disputed. The Gaza Health Ministry stated on the same day as the operation that the number of victims "has risen to 210 martyrs and more than 400 wounded." Later that day the number was updated to 274 Palestinians killed during the operation with around 700 wounded. Tanya Haj-Hassan, a paediatric intensive care doctor with Doctors Without Borders, stated that Al-Aqsa hospital, where 109 Palestinians including 23 children and 11 women and over 100 wounded victims were transported, was a "complete bloodbath." Another 100 people killed in the attacks were taken to al-Awda hospital. It is not known how many combatants are included in these counts.

According to the IDF, Hamas pays Palestinian families to hold the hostages in their houses, which may account for the high casualties. In addition, a large firefight occurred as IDF special forces were attempting to extract the hostages, reportedly coming under fire from dozens of militants with RPGs and machine guns when their vehicle became stuck. The IDF then called in airstrikes to cover their evacuation. The IDF estimates the number of casualties from the operation was “under 100.”

According to Hamas spokesman Abu Obaida, the operation resulted in the deaths of several other Israeli hostages, which IDF spokesman Peter Lerner dismissed. The day after the operation, Hamas's armed wing uploaded a video to its Telegram channel appearing to show corpses of three hostages that were reportedly killed during the rescue operation. The faces of the corpses were obscured to prevent identification.

On the Israeli side, the operation resulted in the death of Yamam officer Chief Inspector Arnon Zamora [he]. The rescue operation was renamed in his honor as "Operation Arnon", and a pedestrian bridge in Petah Tikva has been renamed "Operation Arnon Bridge [he]".

Argamani was reunited with her father and transported to Sheba Medical Center to be reunited with her mother, where she was being treated for terminal brain cancer. Her father told reporters "Today is my birthday, and what a present I received". During a phone call with Argamani, Israeli Prime Minister Benjamin Netanyahu said that "we didn't give up on you for a moment." Her mother died less than a month later.

Arab Israeli actress and TV presenter Lama Tatour was fired after she created a post on Instagram regarding Noa Argamani's appearance. She wrote: "this is what a girl that's been in captivity for nine months looks like? [...] This is what innocent women and children are being killed for in Gaza?" and said that Argamani's eyebrows looked better than her own. Some interpreted her comments as "insensitive" and "mocking" Argamani's appearance.

Israeli war cabinet member Benny Gantz postponed a scheduled news conference the night of the raid, which coincided with his deadline to resign if Prime Minister Benjamin Netanyahu did not present a new plan for the war. The following day, he resigned.

Allegations of the United States military constructed floating pier in Gaza being used in the IDF operation, were seen after a video showing an IDF helicopter taking off from the beach with the pier in the background began to circulate online on 8 June. Two United States officials responded to the claims, stating that the pier was only used for humanitarian aid and the helicopter was used to return the hostages into Israel and had landed south of the pier but not within the cordoned off area. The U.S. had promised aid groups the pier would be a no-go area for Israeli forces and the UN has put aid operations at the pier on hold while it investigates and decides whether the Israeli usage, real or apparent, of the pier facilities and the perception of that by Palestinians, mitigates against continued engagement at the pier. Oxfam and other aid organizations said they are waiting for answers from the U.S. government.
