The Taliban had taken control of positions near the main roads of the area and this will give them the capacity to cut off communications between main cities whenever they wish, NDTV said Thursday.
Peshawar, the provincial capital of the North West Frontier, is a key post on the supply route to the US-led NATO troops in Afghanistan.
A US report also said that Taliban militants were holding at least 15 paramilitary soldiers.
The authorities in north-west have also found the bodies of 22 pro-government tribesmen who were kidnapped by local Taliban militants on Monday.
Pakistani officials also issued an alert that members of a terrorist group have entered southern Sindh province and may kidnap British and American nationals working there for ransom.
Sources told Geo News channel that the terrorists might abduct foreign nationals and take them to the troubled tribal areas bordering Afghanistan, which are a stronghold of the Pakistani Taliban.
The developments came after the Prime Minister and military agreed a broad outline to counter the threat of militancy.
Some political analysts say the group has already established a parallel government in some parts of the country.
