An Israeli airstrike hit the northern gate of a field hospital in the Gaza Strip on Tuesday, wounding 10 people, including three medics and seven patients, a spokesman for the hospital said.

The strike hit the Kuwaiti Field Hospital in the Muwasi area, where hundreds of thousands of people have sought shelter in sprawling tent camps.

Saber Mohammed, a spokesman for the hospital, said two of the patients were critically wounded.

There was no immediate comment from the Israeli military.

The military has struck hospitals on several occasions during the 18-month war, accusing Hamas militants of hiding out in them or using them for military purposes.

Hospital staff have denied the allegations and accused Israel of recklessly endangering civilians and gutting the territory's health system.

On Sunday, Israel struck the last major hospital providing critical care in northern Gaza after ordering an evacuation. A patient died during the evacuation, and the strike severely damaged the emergency room, pharmacy and surrounding buildings, according to Al-Ahli Hospital.

The Episcopal Diocese of Jerusalem, which runs the hospital, condemned the strike.

Israel said it targeted a Hamas command and control centre within the facility, without providing evidence. Hamas denied the allegations.

The war began when Hamas-led militants attacked southern Israel on October 7, 2023, killing some 1,200 people, mostly civilians, and abducting 251.

Fifty-nine hostages are still inside Gaza, 24 of whom are believed to be alive, after most of the rest were released in ceasefire agreements or other deals.

Israel's retaliatory offensive has killed nearly 51,000 people, according to Gaza's Health Ministry. It does not say how many were civilians or combatants but says women and children make up more than half of the dead.

The offensive has destroyed a vast part of the territory and displaced around 90 per cent of its population of roughly 2 million Palestinians.
