At least two suspected militants were killed in a clash with the Aman Lashkar, a pro-government tribal militia, near the Pak-Afghan border in Khyber Agency on Sunday.

The clash began after the militants attacked a militia post in the Zakhakhel area in tehsil Ladi Kotal with heavy arms, according to security sources.

The sources said that no members of the Aman Lashkar were harmed in the attack, whereas two militants were killed in retaliatory firing.

Members of the militia recovered the bodies of the dead militants. Some of the attackers fled to Afghanistan, the sources added.

Security personnel remain vulnerable to attacks by militants in areas near the Pak-Afghan border.

Khyber Agency is one of the most sensitive of these areas. On Oct 3, a security official, Naib-subedar Azher Ali, lost his life in an alleged terrorist attack on the Pakistani post in Khyber Agency from across the Afghan border.

In September, 22-year-old lieutenant Arsalan Alam was martyred in a terrorist attack on a post in Rajgal valley.

The army recently concluded Operation Khyber IV in the Rajgal valley to effectively check and guard against" movement across the porous border in Khyber Agency.
