Human rights advocates are urging Saudi Arabian officials to stop the mass firing of Yemeni workers — a move that puts them at risk of being deported to Yemen if they cannot find another employer to sponsor them. Saudi authorities in July reportedly announced new regulations requiring businesses to limit the number of Yemeni and other foreign employees on staff. Human Rights Watch says the policy could put hundreds of workers at risk of being sent back to the Saudi-led, U.S.-backed war in Yemen, which has sparked the world’s worst humanitarian crisis.
