- Bombing at a Shrine in Pak's Sindh province on Thursday claimed 88 lives
- Terror group, ISIS had claimed responsibility for the attack
- Pak Army has launched combing operations across the nation
The media wing of the army, ISPR, said a "sizeable" number of suspects have also been arrested since last night, when a Islamic State bomber blew himself up at the popular shrine of Lal Shahbaz Qalandar in Sehwan in the southern province.
The statement did not specify where the terrorists were killed or about the arrests and said "details will be shared".
The blast was one of the deadliest in Pakistan in years and a continuation of several terrorist strikes in the country this week, despite the army's offensive against terrorists.
Pakistan Army has launched combing operations across the country, including Punjab province. "Intelligence agencies are making progress to unearth networks behind recent (terrorist) incidents," military spokesman Major General Asif Ghafoor said, without providing details.
Immediately after the blast, Pakistan claimed the bombing was planned in militant sanctuaries across the border in Afghanistan, threatening renewed hostilities between Kabul and Islamabad.
The army claimed it has found linkages to terrorist support networks operating from Afghanistan and it has closed the border due to security reasons after the bombing last night.
Pakistan Army began an operation in Shalman area near the Pakistan-Afghan border, using heavy artillery fire, reports said. The border with Afghanistan at Torkham has been shut.
"No cross-border or unauthorised entry will be allowed into Pakistan from Afghanistan," it said.
Afghan diplomats were summoned yesterday to General Headquarters in Rawalpindi by the Army, which lodged a protest over the use of Afghan soil by terrorists to carry out attacks in Pakistan.
The Afghan officials were also handed over a list of 76 terrorists hiding across the border and directing or supporting terrorist activities in Pakistan, the statement said.
"Afghan government has been asked to target them and hand them over to Pakistan." Army chief Qamar Javed Bajwa assured the people, saying the "hostile" agenda will not be allowed to succeed "whatever it may cost".
"Army is for security of people of Pakistan against all types of threat. Nation to stay steadfast with full confidence in their security forces," he was quoted as saying in the statement.
