Israel said Monday that it has terminated the agreement facilitating the work of the U.N. agency for Palestinian refugees, the main aid provider in Gaza, in what appeared to be a step to implement legislation passed last month that would sever ties with the agency and prevent it from operating in Israel.

Two bills making their way through Israel’s parliament would sever its ties with the U.N. agency for Palestinian refugees, strip it of legal immunities and effectively bar it from operating in Israel and the Palestinian territories.
