Peshawar, Pakistan. Afghanistan said Sunday it killed 58 Pakistani soldiers in overnight border operations, in response to what it called repeated violations of its territory and airspace.

Earlier in the week, Afghan authorities accused Pakistan of bombing the capital, Kabul, and a market in the country’s east. Pakistan did not claim responsibility for the assault.

The Taliban government’s chief spokesman, Zabihullah Mujahid, said Afghan forces have captured 25 Pakistani army posts, 58 soldiers have been killed, and 30 others wounded.

“The situation on all official borders and de facto lines of Afghanistan is under complete control, and illegal activities have been largely prevented,” Mujahid told a press conference in Kabul. There was no immediate confirmation from Pakistan about casualties.

The Taliban government’s Defense Ministry said early Sunday morning its forces had conducted “retaliatory and successful operations” along the border.

“If the opposing side again violates Afghanistan’s territorial integrity, our armed forces are fully prepared to defend the nation’s borders and will deliver a strong response,” the ministry added.

The Torkham border crossing, one of two main trade routes between the two countries, did not open on Sunday at its usual time of 8 am.

Pakistan accuses Afghan authorities of harboring members of the banned group Tehreek-i-Taliban Pakistan. Islamabad says the group carries out deadly attacks inside Pakistan, but Kabul denies the charge, saying it does not allow its territory to be used against other countries.

Pakistani Prime Minister Shehbaz Sharif condemned the Saturday night assault and said the country's army “not only gave a befitting reply to Afghanistan’s provocations but also destroyed several of their posts, forcing them to retreat.”

Qatar's Foreign Ministry expressed concern over the escalations and the potential repercussions for the security and stability of the region. It urged both sides to prioritize “dialogue, diplomacy and restraint.”

A senior Pakistani security official, speaking on condition of anonymity because he was not authorized to talk to the media, said Afghan forces opened fire in several northwestern border areas in the province of Khyber Pakhtunkhwa, including the districts of Chitral, Bajaur, Mohmand, Angoor Adda and Kurram.

The official also said troops responded with heavy weaponry near Tirah in Khyber district and across the frontier in Afghanistan’s Nangarhar province.

A second Pakistani security official, who also spoke on condition of anonymity because he was not authorized to talk to the media, said at least one person was killed and another wounded when a mortar shell fired from the Afghan side landed in Tiri village, Kurram district.

The two countries share a 2,611-kilometer (1,622-mile) border known as the Durand Line, but Afghanistan has never recognized it.
