In Ethiopia, at least seven people, including several children, were killed Friday when government forces attacked a kindergarten in the northern Tigray region. The attack in Tigray’s regional capital, Mekelle, came as a five-month truce between Ethiopia’s military and separatist rebels unraveled, threatening to worsen a humanitarian crisis that’s already among the worst in the world. The U.N. says the fighting has left about half of Tigray’s 6 million residents on the brink of famine.
