The 209th Shaheen Corps of the Afghan Military in the North said the airstrikes were carried out in the vicinity of Khwaja Sabs Posh district.
A statement by the Shaheen Corps stated that a large number of Taliban militants had gathered in Khwaja Qashri area, apparently planning attacks.
The statement further added that the Afghan forces carried out at least five airstrikes targeting the gathering which left at least 15 militants dead.
The airstrikes were carried out at around 1:30 pm local time and as a result at least eight militants also sustained injuries, the Shaheen Corps added.
At least two vehicles and three motorycles belonging to Taliban militants were also destroyed during the airstrikes, Shaheen Corps said.
The anti-government armed militant groups including Taliban militants have not commented regarding the report so far.
The latest airstrikes in Faryab have been carried out as the government is observing a ceasefire but the Afghan officials had earlier said any aggression by the militants would be responded accordingly.
