According to the Afghan army officials, the helicopter made an emergency landing due to bad weather condition in Pashtunkot district.
Provincial police chief Syed Aqa Saqib said at least 13 soldiers of the Afghan National Army (ANA) are missing and there are fears that the soldiers have been taken hostage by the militants.
Saqib said the main reason behind the emergency landing of the helicopter has not been ascertained so far and efforts have been put in place to find out the missing soldiers.
Faryab is among the relatively volatile provinces in northern Afghanistan where anti-government armed militant groups are actively operating in a number of its districts and often carry out insurgency activities.
This comes as at least seventeen people were killed after an Afghan army helicopter crashed in southern Zabul province of Afghanistan earlier in the month of August.
According to the officials, the deaths included five crew members on the Russian-made helicopter along with 12 soldiers being transported to a new post.
