On 13 July 2024, Israeli airstrikes hit the Al-Mawasi area near Khan Yunis in the Gaza Strip during the Israel–Hamas war. The attack killed at least 90 Palestinians, among them women and children, and injured over 300. Israel said that the strike targeted Hamas top leaders. Survivors reported that they were targeted without warning in an area they were told was safe.

Following the Israeli invasion of the Gaza Strip, Israel ordered Palestinian civilians there to evacuate to designated humanitarian safe zones, including Al-Mawasi in December 2023. During the attack on 13 July 2024, Israel dropped eight 2,000-pound bombs on al-Mawasi, at least one of which was manufactured in the United States. Israel said that it had targeted and killed the military commander of Hamas, Mohammed Deif, as well as Commander of the Hamas Khan Younis Brigade, Rafa Salama. Hamas initially denied the death of Deif.

Following the airstrikes, Israeli quadcopter aircraft waited for the ambulance and civil defence teams and opened fire as soon as they arrived, according to eyewitnesses, a local journalist and the Euro-Mediterranean Human Rights Monitor. Two members of the Palestinian Civil Defence were killed by this attack.

The Mawasi attack led to international condemnations of Israel from Arab countries, the European Union and the United Nations. The EU called for an independent investigation and accountability, describing the attack a possible war crime.

During the Israel–Hamas war, many civilians in Gaza were ordered by Israel to evacuate to humanitarian safe zones. In December 2023, the Israel Defense Forces had declared Al-Mawasi a humanitarian safe zone but had attacked it in May and June 2024. In the weeks preceding the attacks, Israel had expanded the "safe zone" to parts of Khan Yunis, and hundreds of thousands of Palestinians had evacuated there.

The IDF said that it had intelligence that Mohammed Deif and another Hamas commander, Rafa Salama, were located in a "compound" bordering the al-Mawasi area safe zone. Mohammed Deif is known for evading multiple assassination attempts by Israel. Allegedly, both Deif and Salama were key planners of the 2023 Hamas-led attack on Israel.

An IDF spokesperson said: "If Hamas senior leaders think they'll build a compound and hide in a compound in an area where we called for them [civilians] to move to, we will hunt them down" Al Jazeera correspondent, Hamdah Salhut, said that Israeli forces "commonly" claim civilians are being used as human shields by Hamas to justify attacking safe zones: "We have seen time and time again attacks on areas where there are displaced Palestinians in the tens of thousands."

According to a Palestinian civil defence spokesperson, the Israeli attack targeted several tents housing displaced Palestinians as well as a separate house located some distance away. The IDF said that it had targeted Mohammed Deif with at least five precision-guided missiles directed at a building located in a "civilian environment" not a tent camp.

Based on videos and photos, The New York Times concluded that two airstrikes had occurred— the first hit a building and left a 60-foot crater consistent with a 2,000-pound bomb. The second, smaller strike hit a busy street immediately in front of two emergency rescue vehicles about 100 yards away from the building. Two military experts said that the Israeli soldiers launching the airstrikes would have been able to see the marked emergency vehicles: "any Hamas targets carry enough military necessity that any civilian loss is considered proportional."

According to The Wall Street Journal, the IDF dropped eight 2,000-pound bombs on al-Mawasi. At least one of the bombs used in the attack was manufactured in the United States.

According to a local Al Jazeera correspondent, warplanes hit Al-Mawasi with "five bombs and five missiles". The Gaza civil defense spokesperson stated, "We went to the location and saw children, women and men torn to pieces. The tents caught fire and burnt. They used such powerful bombs that bodies were buried underground". An eyewitness reported that the site of the airstrike looked like an "earthquake" had hit. A correspondent for The New Arab reported that Israeli airstrikes also targeted rescue teams as they attempted to help wounded victims, killing some rescuers.

According to The Jerusalem Post, Deif's assassination was carried out based on intelligence from a local postman. The postman, who was involved in delivering messages and gathering information about Hamas operations, saw Mohammed Deif during his route and reported his location to the Israeli Defense Forces (IDF). The IDF then executed the assassination based on this information.

Eyewitnesses and Euro-Mediterranean Human Rights Monitor said that after the attack, squadrons of quadcopter aircraft that waited for the ambulance and civil defence teams and opened fire as soon as they arrived. A journalist on the scene stated that Israeli forces "directly targeted" civil defense teams.

According to the Palestinian Civil Defence, two members were killed by the attack. A survivor of the airstrike stated, "Blood was everywhere, shreds of dead bodies were on the ground, kids covered in blood".

The PRCS said that its ambulance crews attended to 102 injured patients and recovered 23 bodies after the attack, 20 of the wounded and 21 bodies were transferred to the Red Crescent's al-Quds Field Hospital, and 22 of the injured were transferred to al-Amal Hospital. The Gaza Health Ministry reported that there were at least 90 dead and at least 300 wounded in what it called a "brutal massacre by the occupation". According to Hamas spokesperson Abu Zhuri, all those killed were civilians.

According to Medical Aid for Palestinians, the Nasser Hospital in Khan Yunis was "overwhelmed" and unable to take in the large numbers of wounded patients. A United Nations official, Scott Anderson, described the aftermath at Nasser Hospital as "some of the most horrific scenes I have seen in my nine months in Gaza". The World Health Organization stated they had dispatched 50 foldable beds and 50 stretchers to increase capacity at the Nasser Medical Complex.

The IDF confirmed that Salama was killed a day after the strike. Hamas did not confirm the report. On 1 August, the IDF reported that it confirmed Deif was also killed in the strike, along with "other terrorists", after an intelligence assessment. Hamas did not confirm or deny the report.

Hamas dismissed the IDF's claims that it had targeted its leaders, labeling them as "false allegations" that aimed to "cover up the scale of the horrific massacre".

According to the Saudi channel Al-Hadath, Rafa Salama was killed in the strike while Deif was seriously wounded. According to both Israeli and Hamas sources, the attack on al-Mawasi impacted the ceasefire negotiations, but they were still ongoing.

By early November 2024, Hamas acknowledged Mohammed Deif's death and confirmed that contact with him was lost following the strike. Two people, including a courier, were questioned on suspicion of helping Israel locate Deif and Salama.
