The troops stationed at the border posts valiantly repulsed the terrorist attack, killing three infiltrators. Scores of militants were also wounded in an intense exchange of fire, the ISPR statement read.

Pakistan and Afghanistan share a long porous border, which comprises difficult-to-access areas, high mountain passes and treacherous terrain, making it difficult to secure every inch of the frontier.
