At least 20 people died Sunday when a Saudi-led coalition airstrike hit a wedding party in northern Yemen. Most of the dead were reportedly women and children who were gathered in one of the wedding party tents. The bride was among the dead. Medics and residents said more than 46 others—including 30 children—were also injured. The attack on the Yemeni wedding party was one of at least three airstrikes over the weekend that killed Yemeni civilians. A family of five died in an airstrike in the province of Hajjah. And 20 civilians died on Saturday when fighter jets bombed a bus near the city of Taiz. Earlier this month, U.N. Secretary-General António Guterres said Yemen had become the world’s worst humanitarian crisis. We speak to Shireen Al-Adeimi, a Yemeni doctoral candidate at Harvard University.
