Three women and an 11-month-old baby were among five people killed in an Israeli strike on a house in Gaza City on Sunday, a spokesman for the Hamas-run health ministry told AFP.
Ashraf al-Qudra said the five had died in the strike on the three-storey building in the northern Nasser district, which also injured 10 people.
Most of the victims were from the same family, he said, naming them as Suheila al-Dallu, 50, Samah al-Dallu, 22 and 11-month-old Ibrahim al-Dallu.
A 70-year-old woman, believed to be from the same family, was also killed but her name was not immediately available.
A man called Abdullah Mohammed al-Muzanna, 22, was also killed in the strike which completely levelled the building, and raised the overall toll of Palestinians killed to 57 in nearly 100 hours of relentless Israeli air strikes.
More than 600 people have been injured in the Israeli bombing campaign, which began on Wednesday afternoon.
