In Yemen, hospitals struggled to care for the wounded after a U.S.-backed Saudi coalition bombed a funeral hall in the capital Sana’a, killing at least 140 mourners and wounding more than 500 others. Survivors spoke of back-to-back bombings during a funeral service for the father of an official with the rebel Houthi government, which controls Sana’a.

Salim Saleh Rowaishan: “There were over 800 people in the hall, including the elderly and children. Suddenly we heard the sound of airplanes, and then the bombing took place. The first bomb ripped through the ceiling and exploded, with the basement destroyed, as well. I was injured and was at a loss. The heat made me feel I was burning. I got up and ran toward the door, where people came in to rescue us. Just then, the second bomb came and hit those people coming to rescue us.”

Thousands of Yemenis gathered at the United Nations’ building in Sana’a on Sunday calling for an international investigation into the assault. This is protester Aamer Hussein Al-Salimi.

Aamer Hussein Al-Salimi: “We came out to the United Nations today to call for our human rights and to denounce this unprecedented massacre that took place yesterday at the mourning hall. Where are the human rights? Where is the U.N.? Where is the world?”

The Obama administration on Saturday condemned the airstrikes, saying in a statement, “U.S. security cooperation with Saudi Arabia is not a blank check.” The attack was carried out with warplanes and munitions sold to the Saudi-led coalition by the United States. The U.S. Air Force continues to provide midair refueling to Saudi warplanes. The latest attack came as the U.N. warned the civil war is leading to famine in Yemen, where some 1.5 million children are currently malnourished and 28 million people are short of food.
