The air campaign waged by the Saudi-led, U.S.-backed coalition in Yemen has been increasingly criticized by human rights activists over civilian deaths. Airstrikes account for 60 percent of the 3,200 civilians killed in the conflict, according to the United Nations, which has criticized coalition strikes that hit markets, clinics and hospitals.
