"Two hundred to 300 displaced people killed in occupation (Israeli) strikes on the yard" of the Ahli Arab hospital in central Gaza, the ministry said.

"Hundreds of victims are still under the rubble," it added.

The media office of Gaza's Hamas government described the attack as a "war crime".

"The hospital was housing hundreds of sick and wounded, and people forcibly displaced from their homes" because of other strikes, a statement said.

An Israeli military spokesman would not immediately confirm its forces bombed the hospital.

"We will look into it ... the strike happened just a short while ago, " Daniel Hagari said in a televised press briefing.

Around 3,000 people have been killed in Israeli air strikes across the Gaza Strip since the war erupted on October 7.

More than 1,400 people in Israel have been killed, the majority gunned down by Hamas militants who crossed from Gaza and attacked border communities.
