Security forces have killed 15 terrorists who were trying to infiltrate through the Pakistan-Afghanistan border opposite North Waziristan District, the military’s media wing said on Thursday, adding that the engagement lasted for 36 hours. According to the Inter-Services Public Relations (ISPR), security forces detected the "movement of a group of khawarij belonging to Indian-sponsored Fitna Al Khawarij during the night of August 31 and September 1." Fitna al-Khawarij is the state-designated term for the banned Tehreek-e-Taliban Pakistan (TTP). “Own troops responded professionally and with patience to engage them successfully,” the statement said. The ISPR further added that as a result of "precise and skillful engagement" that lasted for 36 hours, 15 terrorists were killed. During the follow-up sanitisation operation, a significant quantity of weapons and ammunition were also recovered from the killed terrorists, which ISPR said had “further exposed the nefarious designs of Khawarij and their facilitators” seeking to “disrupt peace and stability in the country”.

The ISPR further stated that the Afghan Taliban regime "has consistently failed to ensure effective border management and honour its international obligations." Pakistan has repeatedly accused terrorist groups based in Afghanistan of carrying out attacks inside the country and demanded that Kabul take action against them. The Afghan Taliban government has rejected accusations that it allows its territory to be used for attacks against Pakistan. Pakistan’s security forces " remain resolute and unwavering in their commitment" to protecting the country’s borders, it added. "Sanitisation operation is being conducted to eliminate any other Indian sponsored Kharji found in the area as relentless Counter Terrorism campaign under the vision “Azm e Istehkam” (as approved by Federal Apex Committee on National Action Plan) by security forces and law enforcement agencies of Pakistan will continue at full pace to wipe out the menace of foreign-sponsored and supported terrorism from the country," the statement concluded. Terrorism is a growing problem for Pakistan, with the number of attacks rising every year since 2022, according to Armed Conflict Location & Event Data (ACLED), a global monitoring organisation. Data from ACLED shows attacks in Pakistan rose nearly fourfold to 2,425 in 2025 from 658 in 2022, and over the same period, TTP attacks increased more than sevenfold to 838 from 118.
