The Gaza civil defense agency said an Israeli air strike early on Tuesday killed 10 members of Hamas chief Ismail Haniyeh's family, in an attack the Israeli military did not immediately confirm. 

The strike hit the Haniyeh family home in Al-Shati refugee camp, in the northern Gaza Strip, said Mahmud Basal, spokesman for the Hamas-ruled territory's civil defense. 

"There are 10 martyrs ... as a result of the strike, including Zahr Haniyeh, sister of Hamas political bureau chief Ismail Haniyeh," Basal told AFP. He said a number of bodies were likely still under the rubble but "we do not have the necessary equipment" to extract them. 

Civil defense crews transferred the bodies to Al-Ahli hospital in nearby Gaza City, Basal added, also reporting "several wounded" in the attack. 

The Israeli military on Tuesday said its air forces attacked two buildings used by Hamas in Al-Shati and Darj Tupah region in the northern Gaza Strip on Monday night, but did not provide information on any casualties. 

Haniyeh, Hamas's Qatar-based political leader, lost three sons and four grandchildren in an Israeli strike in April in central Gaza, with the military accusing them of "terrorist activities". Haniyeh at the time said that about 60 members of his family had been killed since the Palestinian militant group's war with Israel broke out on October 7.
