At least eight Afghan National Army (ANA) soldiers were killed in a USA airstrike at an army checkpoint in eastern Logar province early on Monday, according to local media reports.
An American military official said he was “aware of an incident involving U.S. forces in Logar province this morning”.
The zone chief, Mohammad Rahim Amin, said the North Atlantic Treaty Organisation find was also likely a slip, from weak matching with in location in which Taliban insurgents are extremely working.
The Taliban shot at the rescue team, forcing them to leave the bodies behind.
The US military and its coalition partners formally ended their combat mission in the country past year, leaving Afghan soldiers and police to fight a resilient Taliban nearly on their own.
The only active worldwide fighting units are assisting Afghan special forces, and that is the mission that the helicopters believed to have been involved in the attack on Logar would have been engaged in.
The two sides agreed to meet again in the coming weeks, drawing global praise.
Death of civilians and Afghan army personnel in Friendly fire has become a contentious issue in the country.
It is rare for USA or coalition bombings to kill Afghan troops, but it has happened before.
The Afghan army does have some attack helicopters. The result of the investigation for that incident revealed a lapse on the part of the American forces, specifically in the area of communication and in understanding the capabilities of the aircraft used, AFP reported.
