In Ethiopia, more than 50 people were killed and more than 70 injured in the northern Tigray region Tuesday after an airstrike ripped through a school housing people displaced by fighting between Ethiopia’s military and separatist rebels. It’s among the deadliest attacks carried out in Tigray since conflict erupted in November of 2020, leaving thousands dead and millions displaced from their homes. On Wednesday, both Ethiopia’s government and Tigray rebels said they had accepted an African Union invitation to join peace talks in South Africa aimed at ending the conflict.
