The Pak-Afghan border in Kurram Agency remained closed on its fourth consecutive day Monday over security reasons.
Closure of border has suspended transportation and commuting at both sides of the border, causing long queues of vehicles loaded with fruit and other goods.
The border was closed four days back after security personnel foiled major terror plot and killed the suicide bomber, entering Pakistani territories. Two security men were injured in the attack.
Security sources said the border had been closed over security reasons.
