Israel's envoy to the UN, Danny Danon, said Israel will terminate all collaboration, communication and contact with UNRWA or anyone acting on its behalf, repeatedly accusing the organization of undermining its security.

UNRWA chief Philippe Lazzarini called Israel's actions a "relentless assault" on his organization. He said it is harming the lives and future of Palestinians across the occupied Palestinian territory, and eroding their trust in the international community, jeopardizing any prospect for peace and security.

Last October, Israel passed a law banning the UN Palestinian refugee agency UNRWA from operating in the country despite opposition from the United States and several European countries.
