Two soldiers were matryred in an exchange of fire with terrorists attempting to cross the fence along the Pak-Afghan border into Khyber Pakhtunkhwa's Kurram district, the military's media affairs wing said on Wednesday.

According to the Inter-Services Public Relations (ISPR), terrorists from inside Afghanistan attempted to infiltrate into Pakistan in the night between October 26 and October 27.

"Troops initiated a prompt response and thwarted the attempted illegal crossing by engaging the terrorists," the ISPR said in a statement.

It added that during the exchange of fire with the terrorist, 24-year-old Lance Naik Asad, a resident of Kurram, and 21-year-old Sepoy Asif, a resident of Lakki Marwat, embraced martyrdom.

"Pakistan strongly condemns the use of Afghan soil by terrorists for activities against Pakistan and expects that [the] interim Afghan government will not allow such activities against Pakistan in [the] future," the ISPR said.

It added that the Pakistan Army was determined to safeguard the country's frontiers against the menace of terrorism, and "such sacrifices of our brave soldiers further strengthen our resolve."

Last week, two soldiers were martyred and two others injured in a terrorist attack in the North Waziristan tribal district.

According to officials , fighting between security forces and terrorists had broken out near Miramshah, the headquarters of North Waziristan, and one terrorist had also been killed in the exchange of fire.
