The United Nations Security Council on Monday demanded a cease-fire in Gaza during the Muslim holy month of Ramadan, its first demand to halt fighting. The United States abstained on the resolution, which also demanded the release of all hostages taken captive during Hamas’ Oct. 7 surprise attack in southern Israel, which sparked the war. The measure does not link the demand for the hostages’ release to the call for a cease-fire during Ramadan, which ends April 9.

Immediately after the vote, U.N. Secretary-General António Guterres said on social media that the “resolution must be implemented. Failure would be unforgivable.”
