TEL AVIV, Israel -- Israel faced sharp criticism as it stopped the entry of all food and other supplies into Gaza on Sunday and warned of “additional consequences” for Hamas if a fragile ceasefire isn't extended. Mediators Egypt and Qatar accused Israel of violating humanitarian law by using starvation as a weapon.

U.S. envoy Steve Witkoff is set to attend talks with Israel and Hamas in Qatar on Tuesday. The Israeli delegation left for Doha on Monday, an Israeli official said.
