The Pakistani newspaper Dawn reported, citing local sources, that Pakistani border forces clashed with militants in the Maidan area of Lower Dir district in Khyber Pakhtunkhwa province on Saturday.
The Pakistani army has not yet commented on the incident, and no exact details about potential casualties have been released.
According to Dawn, the clashes occurred when "terrorists" attempted to enter Pakistan from the border areas with Afghanistan. Pakistani security forces surrounded the militants at three different points, and army helicopters conducted airstrikes on militant hideouts.
The severity of the conflict prompted the army to dispatch additional troops to the area.
