The governor of Afghanistan’s Kunar Province has reported a US drone strike against the Manogi District has killed at least three civilians, all children, and wounding seven others.

A survivor of the explosion says that the drone hit their house, knocking him unconscious. He reported seven members of his family were hospitalized, and denied that they had done anything wrong.

NATO was quick to deny the report, saying that they took allegations “very seriously,” but that their own reports on operations in the area didn’t confirm any such incidents in the province.

Civilian deaths in NATO air strikes have been a huge problem throughout the war, with the US often promising an “investigation” that never seems to actually conclude into exactly what happened.
