The Kamal Adwan hospital in north Gaza is no longer functioning and patients have been evacuated after a raid by the Israeli troops, putting the collapsing health services in further peril, a World Health Organisation official said on Monday.
Gazan authorities said Israeli forces last week used a bulldozer to smash through the perimeter of the hospital, claiming it was used by Hamas fighters.
Reuters could not independently verify the accounts.
The WHO had said it was urgently seeking information about the hospital.
"What we understand is it's not functional anymore," Richard Peeperkorn, WHO representative for Gaza, told Reuters.
He said two newborn babies were taken home "to their families and with a description how to take care of them", while other patients including infants were evacuated to Al Ahli and Al Shifa hospitals. "Many health workers were reportedly detained," he said.
Most hospitals in Gaza have been put out of operation by the war, with health services in northern Gaza worst affected.
Gaza is home to 2.3 million people, most of whom have been displaced from their homes by the offensive launched by Israel in retaliation for Hamas' October 7 incursion.
Peeperkorn also said that about 4,000 displaced people taking refuge in the grounds of the Nasser medical complex in the southern city of Khan Younis were at risk as Israel pursues military operations there.
