An agreement for a four-day cease-fire in Gaza and the release of dozens of Hamas-held hostages and Palestinians imprisoned by Israel appeared to have hit a last-minute snag when a senior Israeli official said it would not take effect until Friday, a day later than originally announced.

The diplomatic breakthrough promised some relief for the over 1.7 million Palestinians who have fled their homes under weeks of Israeli bombardment, as well as families in Israel fearful for the fate of their loved ones captured during Hamas’s October 7 attack that triggered the war.
