Pakistan has begun to fence its over 2,400-kilometre-long, porous border with Afghanistan.
Pak Army on Tuesday said the phased fencing of entire Pakistan-Afghanistan border has commenced.
It said in the first phase high infiltration-prone border areas in Bajaur, Mohmand and Khyber Agencies are being fenced. In the second phase, fencing of remaining border areas including the restive Balochistan province will be executed.
Pakistan shares a long and porous border with Afghanistan, which runs through mountainous terrain and is largely unpatrolled.
The Durand Line was drawn by the British rulers in 1896 and is disputed by Afghanistan, which also resists Pakistani attempts to erect any border fence.
