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.

Israeli forces killed four aid seekers traveling on Sunday through a military zone south of Gaza City — an area regularly used by Palestinians trying to reach a food distribution point, a hospital and witnesses said.

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.
