Afghan strike forces backed by the US Central Intelligence Agency (CIA) have committed abuses “amounting to war crimes”, according to a new report.
Human Rights Watch (HRW) alleges the troops “committed summary executions and other grave abuses without accountability”.
These include extrajudicial killings, forced disappearances and attacks on healthcare facilities.
Afghanistan’s government told the BBC the current situation was unacceptable.
Disputing the report, the CIA said its covert operations were carried out in “accordance with law and under a robust system of oversight”.
Both the UN and the New York Times have previously highlighted allegations of abuses by Afghan strike teams.
This latest report comes after peace talks between the US and the Taliban collapsed in September.
‘I found my house was rubble’
Two Afghan men from Maidan Wardak province spoke to the BBC about alleged US-backed raids on their home.
One man named Masihurahman said he lost 12 members of his family, including his wife, four daughters and three sons, when a “huge bomb” was dropped on his village.
“They martyred them all,” he said. “When I returned, I found my house in rubble.”
Another man, Wahidullah, said troops broke into his home and dragged him and his family out. He said they took them to the top of a mountain, where Americans “gave them the order” to carry out killings.
