An Israeli airstrike on a refugee camp in north Gaza killed early Saturday five members of the same family and wounded others, hospital officials said.

The strike was one of several on northern Gaza, where the Israeli military says it will expand its military operations against Hamas in Gaza City.

Hospital officials said five of the bodies it received belonged to the Abu Awad family consisting of the parents Mustafa and his wife Samah and three of their children Mina, 12, Leen, 6, and Mohammed, 4.

The officials added that the fourth child, Nour Abu Awad, 10, was critically wounded.

The officials said the family members were killed and wounded in a strike on an apartment in the Shati refugee camp on the edge of Gaza City.

The bodies were taken to Shifa Hospital in Gaza City where they were put in white plastic bags or draped in white cloth in the morgue.

The latest deaths came as Israel's army called Saturday on Palestinians in Gaza City to move to a humanitarian area it designated in the south as it expanded its operations in preparation for seizing the famine-stricken city.

Parts of the city, home to nearly 1 million people, are already considered "red zones," where evacuation orders have been issued ahead of expected offensive.

Aid groups have repeatedly warned that a large-scale evacuation of Gaza City would exacerbate the dire humanitarian crisis.

Palestinians have been uprooted and displaced multiple times during the nearly two-year-long war, with many being too weak to move and having nowhere to go.

Israeli military spokesman Avichay Adraee wrote in X that the army declared Muwasi — a makeshift tent camp in southern Gaza Strip — a humanitarian area and urged everyone in the city, which it called a Hamas stronghold and specified as a combat zone, to leave.

The army said they could travel in cars down a designated road without being searched.

Despite Israel's warnings many Palestinians in Gaza City say they won't leave.

The war started after Hamas-led militants killed around 1,200 people, mostly civilians, and abducted 251 people in their attack on southern Israel on Oct. 7, 2023.

Most have since been released in ceasefires or other agreements.

Israel's retaliatory offensive has killed more than 64,000 Palestinians, according to Gaza's Health Ministry, which does not say how many were civilians or combatants but says women and children make up around half the dead.

The U.N. and independent experts consider it the most reliable source on war casualties.

Israel disputes its figures but has not provided its own.
