CAIRO/GAZA/JERUSALEM >> An Israeli airstrike killed at least 90 Palestinians in a designated humanitarian zone in Gaza on Saturday, the enclave’s health ministry said, in an attack that Israel said targeted Hamas military chief Mohammed Deif.

It was unclear whether Deif was killed. “We are still checking and verifying the results of the strike,” an Israeli military official told reporters.

The militant Islamist group Hamas said in a statement that Israeli claims it had targeted leaders of the group were false and aimed at justifying the attack, which was the deadliest Israeli attack in Gaza in weeks.

Displaced people sheltering in the area said their tents were torn down by the force of the strike, describing bodies and body parts strewn on the ground.

“I couldn’t even tell where I was or what was happening,” said Sheikh Youssef, a resident of Gaza City who is currently displaced in the Al-Mawasi area.

“I left the tent and looked around, all the tents were knocked down, body parts, bodies everywhere, elderly women thrown on the floor, young children in pieces,” he told Reuters.

The Israeli military said the strike against Deif also targeted Rafa Salama, the commander of Hamas’ Khan Younis Brigade, describing them as two of the masterminds of the Oct. 7 attack on southern Israel that triggered the nine-month war in Gaza.

Deif has survived seven Israeli assassination attempts, the most recent in 2021 and has topped Israel’s most wanted list for decades, held responsible for the deaths of dozens of Israelis in suicide bombings.

The Gaza health ministry said at least 91 Palestinians were killed in the strike and 300 were injured, the deadliest toll in weeks in the conflict-shattered enclave.

Al-Mawasi is a designated humanitarian area that the Israeli army has repeatedly urged Palestinians to head to after issuing evacuation orders from other areas.

Reuters footage showed ambulances racing towards the area amidst clouds of smoke and dust. Displaced people, including women and children, were fleeing in panic, some holding belongings in their hands.

The Israeli military published an aerial photo of the site, which Reuters was not immediately able to verify, where it said “terrorists hid among civilians”.

“The location of the strike was an open area surrounded by trees, several buildings, and sheds,” it said in a statement.

The Israeli military official said the area was not a tent complex, but an operational compound run by Hamas and that several more militants were there, guarding Deif.

HOSPITAL ‘FULL OF PATIENTS’

Many of those wounded in the strike, including women and children, were taken to the nearby Nasser Hospital, which hospital officials said had been overwhelmed and was “no longer able to function” due to the intensity of the Israeli offensive and an acute shortage of medical supplies.

“The hospital is full of patients, it’s full of wounded, we can’t find beds for people,” said Atef al-Hout, director of the hospital, adding that it was the only one still operating in southern Gaza.

Israeli Defence Minister Yoav Gallant was holding special consultations, his office said, in light of “developments in Gaza”.

It was unclear how the strike would affect ceasefire talks underway in Doha and Cairo.

“Maybe it’s good, maybe it’s not good. I don’t know about Mohammed Deif, I know that keeping the war is bad for all of us,” said Ayala Metzger, the daughter-in-law of an Israeli hostage who was taking part in a hostage solidarity march just outside Jerusalem on Saturday.

“We need to bring the hostages back,” she told Reuters.

“If (Israeli Prime Minister Benjamin) Netanyahu killed Mohammed Deif then he has his picture of victory so bring them back now.”

ATTACK HIT CALM AREA, WITNESSES SAY

Separately on Saturday, at least 20 Palestinians were killed in an Israeli attack on a prayer hall at a Gaza camp for displaced people in west Gaza City, Palestinian health and civil emergency officials said.

A senior Hamas official did not confirm whether Deif had been present in the attack on Khan Younis and called the Israeli allegations “nonsense”.

“All the martyrs are civilians and what happened was a grave escalation of the war of genocide, backed by the American support and world silence,” Sami Abu Zuhri told Reuters, adding the strike showed Israel was not interested in reaching a ceasefire deal.

Critics have accused Israel of committing genocide against Palestinians, which Israel denies. It characterizes its actions as self-defense to prevent another attack like Oct. 7, though the International Court of Justice ordered Israel in January to take action to prevent acts of genocide.

Hamas-led militants killed 1,200 people and took more than 250 hostages in the cross-border raid into southern Israel on Oct. 7, according to Israeli tallies.

Israel has retaliated with its military action in Gaza that has killed more than 38,000 Palestinians, medical authorities in Gaza say.

Witnesses said the Khan Younis attack came as a surprise as the area had been calm, adding more than one missile had been fired. Some of the wounded who were being evacuated were rescue workers, they said.

“They’re all gone, my whole family’s gone … where are my brothers? They’re all gone, they’re all gone. There’s no one left,” said one tearful woman, who did not give her name.

Rising up the Hamas ranks over 30 years, Deif developed the group’s network of tunnels and its bomb-making expertise, Hamas sources say.

In March, Israel said it killed Deif’s deputy, Marwan Issa. Hamas has not confirmed or denied his death.
