The raids ended a night of relative quiet in which no-one was killed for the first time since Israel launched its relentless aerial assault on rocket-firing militants in the enclave on November 14, Palestinian medics said.

More than 920 people have been injured in the bombing campaign.

Emergency services spokesman Adham Abu Selmiya named the latest victims as Abdel Rahman Hamed, who died in Safina just north of Gaza City, and Mohammed Badr who was killed in a strike on Deir al-Balah in central Gaza.

Earlier he said another three people died in separate strikes on the northern Gaza Strip and a fourth had been killed in an area just south of Gaza City.

Among the latest victims were 15-year-old Yahya Mohammed Awad who was hunting birds near the beach when a missile hit the northern Sudaniya area, and two men who were killed in the nearby town of Beit Lahiya: Yahya Maaruf, a farmer who was working his land, and another man called Bilal Birawi, 20.

And in Mughraqa, just south of Gaza City, another strike killed Mahmud Rizk al-Zahar, he said.

Overnight, the Israeli military said it attacked about 100 targets with a combination of aircraft, warships and artillery, one of which targeted "a financial institution used by Hamas".

Hamas officials and witnesses also told AFP that strikes hit the homes of several leaders within its armed wing, the Ezzedine al-Qassam Brigades.

Monday was the bloodiest day of the Israeli operation since it was launched on Wednesday, with 33 people killed.

During the late evening, a family of four was killed in an attack on Beit Lahiya, and two teenage brothers were killed in Rafah.
