Giving details of the operation, the statement from the army’s media wing Inter-Services Public Relations (ISPR) said a group of terrorists was reported to have infiltrated in Pakistan and was hiding in a compound in the district.
The ISPR said that the security forces cleared the area and started identification of the killed terrorists, whose bodies were held by the security forces, adding that an officer was among the killed Pakistani soldiers in the intense exchange of fire.
It was not clear so far which group was involved in the encounter. However, the army usually blame members of the outlawed Tehrik-e-Taliban Pakistan for such infiltrations.
The Pakistani military had conducted a major operation against the Pakistani Taliban and other militant groups, including foreigners in North Waziristan, in 2014. Many militants were killed and some fled to neighboring Afghanistan, according to the military.
