Officials from Egypt, Israel, the United States and Qatar were expected to meet Thursday in Doha with the aim of resuming talks for a proposed three-phase cease-fire to end the war between Israel and Hamas and free the remaining hostages. But an Israeli official said Israel’s negotiating team was delayed and would likely be dispatched next week.

Israeli Prime Minister Benjamin Netanyahu addressed Congress in Washington on Wednesday as thousands of protesters gathered near the U.S. Capitol to denounce the war. Hamas slammed the speech Thursday and accused Netanyahu of obstructing efforts to end the war and return the hostages.
