Saudi Arabia and the United States have agreed to end U.S. refueling of aircraft from the Saudi-led coalition battling Houthi insurgents in Yemen, ending a divisive aspect of U.S. support to a war that has pushed Yemen to the brink of famine.

The move, announced by the coalition on Saturday and confirmed by Washington, comes at a time when Riyadh, already under scrutiny for civilian deaths in Yemen airstrikes, is facing global furor and potential sanctions over the murder of journalist Jamal Khashoggi at its Istanbul consulate on Oct. 2.

The United States and Britain late last month called for a cease-fire in Yemen to support U.N.-led efforts to end the nearly four-year war, whicch has killed more than 10,000 people and triggered the world's most urgent humanitarian crisis.
