About 90 Patriot missiles from Israel are being sent to Ukraine in a transfer facilitated by the United States, according to a US defense official.

The United States transferred some 90 Patriot air defense interceptors from Israel to Poland this week to then deliver them to Ukraine, Axios reported on Tuesday, citing three sources with knowledge of the operation.

The U.S. military transferred around 90 Patriot air defense interceptors from storage in Israel to Poland this week in order to deliver them to Ukraine, three sources with knowledge of the operation tell Axios.

Diplomats at the United Nations Security Council said planned restrictions on the agency, UNRWA, would imperil Palestinians. Only the U.S. sides with Israel.

Israeli officials have not spelt out how they will enforce the legislation passed last year by Israel's parliament, which accused Unrwa of being complicit with Hamas - an allegation the agency denied.

UN Secretary-General António Guterres has called on the Israeli government to revoke its decision mandating the cessation of all operations by the United Nations Relief and Works Agency for Palestine Refugees (UNRWA) in Jerusalem and the evacuation of its premises by the end of Thursday.
