ISLAMABAD: The Pakistan Army conducted an operation along the Pak-Afghan border in Rajgal valley on Tuesday, the military's media wing said.

An Inter-Services Public Relations (ISPR) statement said the operation was launched "to reinforce troop deployment in Rajgal valley to effectively check and guard against" movement across the porous border in Khyber Agency.

The operation targeted "movement on high mountains and all-weather passes in Khyber Agency," the statement said.

ISPR chief Lt Gen Asim Bajwa claimed "nine terrorist hideouts were destroyed through aerial strikes".

This claim, however, could not be independently verified as journalists do not have access to most parts of the restive agency.

Rajgal valley is located in northern Tirah in Khyber Agency.

Despite heavy military presence on both sides of the border, cross-border movements of militants (in both ways) have been a major area of concern. Investigation into the Bacha Khan University Attack in January established that the mastermind, planners and handlers had used Afghan soil and telecommunication network for executing the deadly strike.

The government has been under persistent pressure from the military to accelerate the steps that were required for an effective execution of its counterterrorism strategy ─ known as the National Action Plan (NAP), a policy agreed by consensus by all political parties after the December 2014 Army Public School tragedy.

Army Chief Gen Raheel Sharif in a statement released by the ISPR on Friday warned that lack of progress on NAP was affecting the consolidation phase of Operation Zarb-i-Azb.

Earlier this month, Pakistan opened a gate at Torkham, one of the busiest crossing points between the two countries and used by 15,000-20,000 people and hundreds of vehicles daily.

Clashes between Pakis­tani and Afghan security forces over the construction of the border gate left four soldiers dead on both sides, including Frontier Corp’s Major Ali Jawad Changezi.

Work on the construction of the gate and allied facilities began in 2014, but Afghan reservations over border regulation kept causing delays.

Further south in Balochistan, Pakistan also completed a 500-kilometre long trench along the porous border to stop the movement of smugglers, militants and other anti-social elements.
