Beit Lahia, Gaza - An Israeli strike in Gaza on Thursday killed a family of four including two children, Palestinian hospital and security sources said.
"The bodies of four members of the Ahmad family were recovered in pieces after an Israeli strike hit a house in the Beit Lahia Project area in the northern Gaza Strip," an official at Al-Shifa hospital in Gaza City said, identifying the children as aged 12 and eight.
The Israeli military, contacted by AFP, said it was checking.
A Palestinian security source in Gaza said Israeli warplanes struck after midnight in Beit Lahia and separately in the heart of the Jabalia refugee camp, with Israeli forces also firing on tents of displaced people and ambulances.
"Israel continues its violations in the Gaza Strip," the security source said.
Israel in October last year agreed to a ceasefire brokered by the US but since then has advanced further into Gaza.
Israeli Prime Minister Benjamin Netanyahu has vowed no let-up in strikes and no pullout from Gaza until Hamas gives up all of its weapons.
Israeli strikes have killed more than 1,300 people in Gaza since the ceasefire was announced, according to the Gaza health ministry.
