A terrorist attack on the Pakistan-Afghanistan border killed five militants and two Afghan security officials Saturday.
Two Pakistani civilians, including a woman and two Pakistani security personnel were injured, Dawn online reported.
Security officials said the militants targeted the Afghan security forces at a border post in Arandu.
The exchange of fire is still continuing as light and heavy weapons are being used.
The Arandu police station has also been damaged.
The border between Pakistan and Afghanistan passes through remote and mountainous terrain making it difficult to police.
The length and porousness of the border allows Taliban militants and other militant groups to easily cross the border without detection at various points.
