The cease-fire was to begin at 8 a.m. local time on Friday. It was to last for 72 hours unless it is extended.

“During this time the forces on the ground will remain in place,” said the announcement, meaning that Israel troops who have entered Gaza can remain. As soon as it takes hold, Israeli and Palestinian negotiators will head to Cairo for talks.

“We urge all parties to act with restraint until this humanitarian cease-fire begins, and to fully abide by their commitments during the cease-fire,” said the statement.
