In Yemen, the charity Save the Children says an airstrike by the Saudi-led coalition killed seven people—including four children—after a missile tore through a hospital Tuesday outside the city of Saada. The chief executive of Save the Children said, “Innocent children and health workers have lost their lives in what appears to been an indiscriminate attack on a hospital in a densely populated civilian area. Attacks like these are a breach of international law.” Meanwhile, thousands of Yemenis rallied in the capital Sana’a Tuesday to protest on the fourth anniversary of the start of the Saudi-led assault on Yemen.
