Washington said it was trying to keep Israel and the Palestinian Islamist group Hamas engaged "if only virtually" in Gaza truce efforts as a U.N. agency warned that humanitarian aid stocks in the devastated enclave have hit "the bottom of the barrel."

Hamas said on Friday it would consult with other militant Palestinian factions on its strategy to negotiate a halt to the war triggered by its Oct. 7 onslaught into Israel.

The United Nations warned that aid for Gaza could grind to a halt within days after Israel seized control of the Rafah border crossing between Gaza and Egypt, closing the vital route on which the enclave of 2.3 million Palestinians depends.
