Pakistan says militants kill 3 troops in cross-border attack

Pakistan's military says a group of "terrorists" from Afghanistan has opened fire on Pakistani security forces along the Afghan border, killing three troops.

In a statement, the military said Friday's cross-border attack took place in the Mohmand tribal region, where Pakistani security forces are fencing the border. It claimed that Pakistani troops returned fire and killed five "terrorists."

The Pakistani army since earlier this year has been constructing a series of fences along the Afghan border, which zigzags across a remote and difficult mountain terrain, to check the movement of militants. Afghanistan objects to the fence construction.

Pakistani and foreign militants who have hideouts there often target Pakistani forces to disrupt the fencing process, which Pakistan says is in the interest of both countries.
