Israeli planes and tanks kept bombarding eastern areas of Gaza City overnight, killing at least 11 people, witnesses and medics said on Tuesday, with Hamas leader Khalil Al-Hayya due in Cairo for talks to revive a U.

Israel's war cabinet voted on Monday to occupy Gaza City, a move condemned at an emergency meeting of the UN Security Council later that day. On Tuesday the Israel Defense Forces (IDF) said it was "at the beginning of a new state of combat".

Israel's new offensive in Gaza City could take weeks to start, leaving the door open for a ceasefire, officials say, even as Prime Minister Benjamin Netanyahu said it would get underway "fairly quickly" and end the war with Hamas' defeat.
