Eight Afghan Taliban, including two key commanders, were killed as Pak security forces repulsed their cross-border attack, sources said on Sunday.

The dead commanders are identified as Khalil and Jan Muhammad, they said, adding that the Pak troops injured 16 Afghan Taliban too.

According to the sources, the unprovoked attack by the Afghan Taliban on the Pak-Afghan border was thwarted on September 7 morning when the Afghan Taliban fired unprovoked heavy weapons at Pakistani checkposts.
