Israeli forces demolished houses in eastern areas of Gaza City overnight, killing at least 11 people in aerial and tank fire, local health authorities said, as the Palestinian Islamist group Hamas told mediators it was ready to resume ceasefire talks.

An airstrike on Gaza City killed at least 12 people as the conflict entered a new phase with an Israeli offensive to rid the city of Hamas and free hostages.

Israel's security cabinet has approved a plan to take control of Gaza City, in a controversial escalation of its war in Gaza. Hundreds of thousands of Palestinians live in the city in the north of the Gaza Strip. It was the enclave's most populous city before the war.
