Israeli strikes killed at least 14 people overnight in Gaza City, said Palestinian health officials, as Israel ramps up its offensive there and urges Palestinians to leave.

Dr. Rami Mhanna, the managing director of Shifa Hospital, where some of the bodies were brought, said the dead included six people from the same family after a strike hit their home early Saturday morning. They were relatives of the hospital's director, Dr. Mohamed Abu Selmiya, he said.

The Palestinian Red Crescent said five other people were killed in another strike close to Shawa Square.

Israel's military didn't immediately respond to questions about the strikes.

In recent days, Israel has been urging hundreds of thousands of Palestinians sheltering in Gaza City to move south to what it calls a humanitarian zone.

Palestinians have streamed out of the city -- some by car, others on foot. Israel opened another corridor south of Gaza City for two days this week to allow more people to evacuate. But many Palestinians in the famine-stricken city are unwilling to be uprooted again, too weak to leave or unable to afford the cost of moving.

Aid groups have warned that forcing thousands of people to evacuate will exacerbate the dire humanitarian crisis. They are urging for a ceasefire so aid can reach those who need it.

The latest Israeli operation, which started this week, likely pushes any ceasefire farther out of reach. The Israeli military, which says it wants to "destroy Hamas' military infrastructure," hasn't given a timeline for the offensive, but there were indications it could take months.

The death count in Gaza has climbed over 65,100, according to Gaza's Health Ministry, which is part of the Hamas-run government, since Oct. 7, 2023, when Hamas-led terrorists stormed into southern Israel and killed around 1,200 people, mostly civilians. Over 250 people were also abducted as hostages. Forty-eight hostages remain in Gaza, with fewer than half believed to be alive.

The Gaza Health Ministry does not say how many of the dead were civilians or militants. Its figures are seen as a reliable estimate by the U.N. and many independent experts. Israeli bombardment in the territory has also destroyed vast areas of the strip, displaced around 90% of the population and caused a catastrophic humanitarian crisis, with experts saying Gaza City is experiencing famine.

On Friday, UNICEF said lifesaving therapeutic food meant for thousands of children in Gaza was stolen from four of its trucks. The statement said armed individuals approached the trucks outside their compound in Gaza City, the drivers were held at gunpoint while the food was taken.

"They were intended to treat malnourished children in Gaza City where famine is declared ... it was a life-saving shipment amid the severe restrictions on aid delivery to Gaza City," said Ammar Ammar, a spokesperson for UNICEF.

In a statement Friday, Israel's army blamed Hamas for stealing the food.

Israel accuses Hamas of siphoning off aid and using it to fund its military activities, without providing evidence. The U.N. says there are mechanisms in place that prevent any significant diversion of aid.

The incidents come as Western countries plan to recognize Palestinian statehood at the United Nations General Assembly in New York City next week. The United Kingdom, Canada, Australia, Malta, Belgium, Portugal and Luxembourg are all expected to recognize Palestinian statehood in the coming days.
