Israel’s military has issued what it’s calling its “final warning” for residents of Gaza City to leave or face death. Israeli Defense Minister Israel Katz said that anyone who remained “will be considered terrorists and terrorist supporters.” The International Committee of the Red Cross announced that it has suspended operations in Gaza City due to Israel’s intensifying assault. The Israeli military is also warning that it will attack Gaza’s Old City — home to Palestinian heritage sites — with “overwhelming force.” Israeli attacks across Gaza since dawn today have killed at least 20 Palestinians and injured dozens of others.
