Israeli forces were withdrawing from a key Gaza corridor on Sunday, Israeli officials and Hamas said, part of Israel's commitments under a tenuous ceasefire deal with Hamas that is moving ahead but faces a major test over whether the sides can negotiate its planned extension.

Hamas said it would release three Israelis on Saturday in the fifth hostage-prisoner swap between the militants and Israel as part of a Gaza ceasefire deal, in exchange for 183 prisoners to be freed from Israeli jails.

Two weeks after the ceasefire between Hamas and Israel took effect, much-needed humanitarian assistance is surging into the Gaza strip. But Palestinians say it’s still an uphill battle to ensure it reaches everyone.
