At least 33 people were killed in an air strike that hit a school sheltering displaced people near the Daesh-held city of Raqqa, a group that monitors the war in Syria said on Wednesday. The Syrian Observatory for Human Rights said it believed the strike was carried out by the US-led coalition against Daesh. Observatory activists had counted at least 33 bodies at the site near the village of Al-Mansoura, west of Raqqa, Observatory Director Rami Abdulrahman told Reuters. The air strike took place on Monday night, he said. The US-led coalition has escalated its aerial campaign against the militant group around Raqqa this month, causing numerous civilian casualties, Abdulrahman said. The nearest Daesh installation to the site of the air strike was a religious school 3 km (1.9 miles) away, he said. A spokesman for the US-led coalition has previously said that it does everything it can to avoid civilian casualties and that it investigates those that are reported as a result of its air strikes. The Syrian Democratic Forces (SDF), a Kurdish-led group of militias backed by the US-led coalition, is fighting to isolate Raqqa ahead of an anticipated assault on the city, which Daesh has used as a command node to plan attacks abroad. The head of the YPG militia, the strongest in the SDF, said last week that the offensive to retake Raqqa would begin in early April but a spokesman for the US Pentagon said no decision had yet been made. — Reuters
