Israeli forces besieged two more Gaza hospitals on Sunday, pinning down medical teams under heavy gunfire, the Palestinian Red Crescent said, and Israel claimed it had captured 480 fighters in continued clashes at Gaza’s main Al Shifa hospital, Reuters reports.

The Palestinian Red Crescent said one of its staff was killed when Israeli tanks suddenly pushed back into areas around Al-Amal and Nasser hospitals in the southern city of Khan Younis, amid heavy bombardment and gunfire.

Israeli forces began operating around Al-Amal, the military said, following “precise intelligence … which indicated that terrorists are using civilian infrastructure for terror activities in the area of Al-Amal.”

Israeli armoured forces sealed off Al-Amal Hospital and carried out extensive bulldozing operations in its vicinity, the Red Crescent said in a statement.

“All of our teams are in extreme danger at the moment and are completely immobilised,” it said.

The Red Crescent said Israeli forces were now demanding the complete evacuation of staff, patients and displaced people from Al Amal’s premises and were firing smoke bombs into the area to force out its occupants.
