In Yemen, a Houthi rebel leader said Sunday that Houthi fighters would support a ceasefire if Saudi coalition forces also halted attacks. Last month, the U.S. called for a ceasefire in Yemen as the diplomatic crisis deepened over the killing of Saudi journalist Jamal Khashoggi. The United States is the largest supplier of arms to the Saudi-led coalition, which has killed at least 57,000 people since the beginning of 2016, according to a recent study, and has brought 14 million Yemenis to the brink of famine. Last week, House Republicans quashed debate on a resolution that aims to end U.S. military support for the Saudi-led war in Yemen.
