The Israeli military said it had delivered hundreds of packets of food to cut-off areas of northern Gaza as fighting raged ahead of a US deadline for Israel to get more aid into the Palestinian enclave or face cuts in military assistance.

Palestinian medics said at least 37 people had been killed in Israeli strikes in several parts of the Gaza Strip overnight and into Tuesday, including 10 people killed in a house in Beit Hanoun and two others in the nearby town of Beit Lahiya.

Four Israeli soldiers were killed in northern Gaza, the military said.

Later, an Israeli strike killed 11 Palestinians in Rafah, medics said. A strike on a house in the Gaza City suburb of Sabra killed a Hamas leader in the city, Waleed Aweida, and his granddaughter. Three other people including his wife were still under the rubble.
