Israel's defence minister has told its military to prepare a plan to "allow any resident of Gaza who wishes to leave to do so", in line with President Donald Trump's proposal for the US to take over the territory and resettle the 2.1 million Palestinians there.

Israel Katz said Gazans should have "freedom of movement and migration" and countries critical of Israel's war with Hamas were "obligated" to take them in.

The US secretary of state meanwhile insisted the resettlement would be temporary during Gaza's reconstruction, though Trump had said it would be permanent.

Palestinian leaders and Arab states have rejected the plan and said that forced displacement would violate international law.
