GAZA STRIP: The Palestinian Red Crescent said on Sunday that Israeli forces were besieging two hospitals in southern Gaza, days after the army began targeting Hamas in and around the territory’s biggest medical center.

Israel has mounted several raids at and near hospitals in Gaza since the war began last October, claiming that fighters are operating in medical complexes — a charge denied by Hamas.

Military vehicles approached Nasser and Al-Amal hospitals in southern Gaza’s Khan Younis as heavy bombardment and gunfire echoed in the area, the Red Crescent said.

The medical organization said a volunteer worker at the hospital was killed by Israeli gunfire on Sunday.

In response to a request for comment on the Red Crescent’s accusation, the military said it was operating in the Al-Amal area and “is not currently operating in the hospitals.”

The Red Crescent said messages broadcast from drones demanded that everyone in Al-Amal leave naked, while forces blocked the gates of the hospital with dirt barriers.

“All of our crews are currently under extreme danger and cannot move at all,” the group added.

Israel’s military said it began an operation in the Al-Amal neighborhood “to continue dismantling terrorist infrastructure and eliminating terrorist operatives in the area.”

The military said the operation began with air force strikes on approximately 40 targets, including military compounds, tunnels and other “terror infrastructure.”

Israeli forces started a major operation early on Monday that is still going on, saying they were targeting Hamas fighters in and around Gaza’s largest hospital, Al-Shifa.

The raid, which Israel vowed will continue until the last fighter is in its hands, has killed some 170 militants, according to the Israeli military.

The military previously raided the facility last November, sparking international criticism.

Israel has also previously carried out operations around Al-Amal, with the Red Crescent in February saying the military had engaged in a multi-day siege of the facility.
