A summit began on Tuesday in Riyadh, Saudi Arabia, to try to resolve the conflict that has been tearing apart Yemen since 2014.  The Yemen war has killed tens of thousands of civilians, broken the country’s economy and divided its people along sectarian lines. Host Marco Werman speaks with Nadwa al-Dawsari, a Yemeni woman and scholar and nonresident fellow at the Middle East Institute, about the goals of the summit, which was not attended by one of the key players in the war, Ansar Allah, also known as the Houthis.
