At least 11 schoolchildren died in an air strike and firing on a Myanmar village, the United Nations children’s agency said, an attack the country’s junta said targeted rebels hiding in the area. Myanmar has been in chaos since the military seized power in a coup in February last year, with nearly 2,300 civilians killed in a crackdown on dissent according to a local monitoring group. The Sagaing region in the country’s northwest has seen some of the fiercest fighting, and clashes between anti-coup fighters and the military have seen entire villages burned down. The UN children’s agency UNICEF condemned Friday’s violence in Depeyin township in Sagaing. “On 16 September, at least 11 children died in an air strike and indiscriminate fire in civilian areas,” UNICEF said in a statement issued Monday. It said schools must be safe and never targeted. “At least 15 children from the same school are still missing,” UNICEF said, calling for their immediate safe release.
