Israeli crews have started bulldozing the Jerusalem headquarters of the U.N. agency for Palestinian refugees. Israel accuses the United Nations Relief and Works Agency of collaborating with Hamas, a charge the agency denies. The demolition marks Israel’s latest step against UNRWA, which provides aid to millions of Palestinian refugees. Israel's Foreign Ministry says the action follows a new law banning the organization. UNRWA calls the move a violation of international law. The agency's supporters argue Israel aims to sideline the issue of Palestinian refugees. The demolition is part of broader efforts to restrict aid groups in the region.
