Israel’s parliament has voted to ban a nearly eight-decade-old United Nations agency that provides essential services for Palestinian refugees, a move that could have devastating consequences for millions of Palestinians living under Israeli occupation.

On Monday, the Knesset passed two bills; one barring UNRWA from activity within Israel, and another banning Israeli authorities from any contact with UNRWA – revoking the 1967 treaty that allows UNRWA to provide services to Palestinian refugees in areas under Israel’s control.
