Several Afghanistan soldiers have been killed in an airstrike by  US forces on Monday. 

At least 10 Afghan soldiers have been killed, officials said on Monday, according to AFP, which revised its initial toll figure of 14, while the local TOLO News reported that 8 soldiers had been killed and 5 were injured. 

The US forces carried out a strike on the Afghan National Security Forces (ANSF) check post in Afghanistan's Logar province, according to Khaama Press

"We are aware of an incident involving U.S. forces in Logar Province this morning, 20 July. This incident is under investigation," a US official was quoted saying by the news site. 

The US airstrikes occurred in a Taliban-dominated area south of Kabul. 

"At 6:00 am today morning, two U.S. helicopters attacked a checkpoint in Baraki Barak district of Logar province. The checkpoint caught fire ... and 10 Afghan army soldiers were killed," district governor Mohammad Rahim Amin told AFP.

However, Afghan officials said the area where the strike occurred was not 'suspicious', and that an Afghan flag was put up at the forces' post. 

"The Afghan flag was waving at the checkpoint in Baraki Barak when the Americans launched their attack," he said.
