Officials in Afghanistan have said at least 10 Afghan soldiers were killed in a US air strike on Monday in eastern Logar province after two helicopters hit an army checkpoint there.
"At 6:00 am today, two US helicopters attacked a checkpoint in Baraki Barak district of Logar province," district governor Mohammad Rahim Amin told AFP.
"The checkpoint caught fire... and 14 Afghan army soldiers were killed," he added.
Amin, later speaking to the AFP news agency, revised his earlier figure of 14 stating that the mistaken attack killed 10 military personnel.
The governor of Logar’s spokesman Din Mohammad Darwesh also confirmed the attack, telling AFP that "the targeted checkpoint was not a suspicious area."
"The Afghan flag was waving at the checkpoint in Baraki Barak when the Americans launched their attack," he said.
The incident occurred south of Kabul, where Taliban fighters frequently carry out attacks on government forces.
US military spokesman Col. Brian Tribus said they are aware of the incident and it is "under investigation."
Civilian casualties from US air strikes have been a controversial issue in Afghanistan, with hundreds of people being killed in the strikes. The number of civilian deaths from the conflict in Afghanistan reached all-time high in the first quarter of 2015, with studies showing at least 100,000 civilians have been killed in the country since the Taliban was toppled in late 2001.
