KABUL — A NATO airstrike hit two Afghan military checkpoints on Monday in a restive province east of the capital, Kabul, killing seven Afghan troops in what an Afghan official described as an accident due to bad coordination.
The Afghan president, Ashraf Ghani, expressed his ‘‘profound sorrow’’ over the tragedy and ordered an investigation into the killings.
The airstrike occurred as coalition helicopters were flying over an area in Logar province, amid clashes between Afghan troops and Taliban fighters, the Afghan Ministry of Defense said.
Insurgents fired toward the helicopters, prompting a response that destroyed one army checkpoint, the ministry statement added. In addition to the fatalities, at least five other army members were wounded, the ministry said.
Logar provincial army commander Abdul Razaq said the early-morning strike took place in the district of Baraki Barak, 30 miles east of Kabul.
District governor Mohammad Rahim Amin said the NATO airstrike was ‘‘likely a mistake, due to bad coordination.’’
Security in Logar has deteriorated in recent months as the Taliban stepped up their attacks on Afghan soldiers and security forces, trying to spread their footprint across the country and take control of some remote regions.
