Palestinian health officials said on Sunday that Israeli forces had shelled the Kamal Adwan Hospital in the northern Gaza town of Beit Lahiya, damaging electricity and oxygen pumps and disrupting urgent surgeries, Reuters reports.

Hussam Abu Safiya, director of the hospital, one of only three barely operational on the northern edge of the enclave, said the facility was hit by around 100 tank shells and bombs, wounding several of the medical staff and patients.

“The situation is extremely dangerous. We have patients in the intensive care unit and others awaiting surgeries. Access to the operating rooms is only possible after restoring electricity and oxygen supply,” Abu Safiya said in a statement.

The hospital is treating 112 wounded people, including six in the intensive care unit, he said.

There was no immediate comment from the Israeli military about Abu Safiya’s account.
