The operation “will aggravate the catastrophic humanitarian situation, endanger the lives of the hostages, and further risk the mass displacement of civilians,” the statement from the nine countries said.

OTTAWA — Canada is joining international partners panning Israel’s plan to take control of Gaza City. Foreign ministers from several countries including Canada, Australia, France, Germany and the United Kingdom say they reject a decision taken by the Israeli security cabinet on Friday to launch an additional large-scale military operation in Gaza.

Canada said on Monday it delivered humanitarian assistance through airdrops to Gaza, which has been under a devastating Israeli military assault for almost 22 months, with Ottawa again accusing Israel of violating international law.
