Hamas has reneged on parts of the Gaza ceasefire and hostage-release deal that was already agreed upon, and is creating a last-minute crisis that prevents the completion of the accord, Israeli Prime Minister Benjamin Netanyahu’s office said.

A source within the Palestinian Hamas movement has told Newsweek that a long-awaited ceasefire deal has been reached with Israel amid the longest and deadliest-ever war in the Gaza Strip. The Hamas source said the group would address the agreement in an upcoming announcement.
