The United Nations said, At least 13 civilians were killed, mostly children, in an air strike by "international forces" in the northern Afghan city of Kunduz late last week
The strike happened between late Friday and early Saturday in support of ground operations conducted by pro-government forces fighting against Taliban militants in the area.
The UN mission in Afghanistan said in a statement, "Initial fact-finding indicates that 10 of those killed were children, part of the same extended family who was displaced by fighting elsewhere in the country."
A NATO spokesperson told AFP the coalition was investigating the claims.
The deaths come as ordinary Afghans continue to bear the brunt of the war in Afghanistan, with more civilians killed in the Afghan war in 2018 than during any other year on record, according to a UN report.
According to the UN, at least 32,000 civilians have been killed and another 60,000 wounded in the last decade.
