Qatar, a key negotiator of the ceasefire, accused Israel of violating the deal. The U.N. relief chief said aid access must be allowed under international law.

Israel said Sunday it is stopping the entry of all goods and supplies into the Gaza Strip. The prime minister's office did not elaborate on the decision but warned of “additional consequences” if Hamas does not accept what Israel says is a U.

Israeli Prime Minister Benjamin Netanyahu on Sunday said his country had cut off all supplies to Gaza “because Hamas steals the supplies and prevents the people of Gaza from getting them.”
