Sixty-four people were killed in Israeli attacks across Gaza in the past 24 hours, the territory's Hamas-run health ministry said.

Two years ago, Gaza’s largest city was sprawling with life. Classrooms brimmed with schoolchildren, markets were full of shoppers and beachside cafes offered respite for those escaping the stresses of a besieged enclave.

Israel's Defence Minister Israel Katz on Sunday vowed to press on with the offensive on the city where famine has been declared, which has raised alarm abroad and objections at home. Katz has said that Gaza City will be razed unless Hamas agrees to end the war on Israel's terms and release all hostages.
