Residents fled a border area between Afghanistan and Pakistan after forces from both sides clashed into the early hours of Tuesday, March 4.
It was the second consecutive day of tit-for-tat gunfire at Torkham, a key crossing between the two countries that has been closed since February 21 because of a dispute between the two neighbors.
The Pakistani official, who spoke on condition of anonymity because he was not authorized to speak with the media, said that gunfire overnight Monday spread fear and panic among residents.
