Ten children, part of the same extended family, were killed by a US air strike in Afghanistan, along with three adult civilians, the United Nations said on Monday.
The air strike early on Saturday was part of a battle between the Taliban and combined Afghan and US forces that lasted about 30 hours in Kunduz, a northern province where the Taliban is strong.
The children and their family had been displaced by fighting elsewhere in the country, the UN Assistance Mission in Afghanistan (UNAMA) said in releasing its preliminary findings about the incident.
UNAMA said in a statement that it is verifying that all 13 civilian casualties occurred around the time of the air strike.
Three other civilians were injured. The incident happened in the Telawka neighbourhood near Kunduz city.
A record number of Afghan civilians were killed in 2018 as aerial attacks and suicide bombings increased, the United Nations said in a February report.
Child casualties from air strikes have increased every year since 2014.
