ISLAMABAD, May 10: Pakistan has fenced a part of its 2,500km-long and porous border with Afghanistan to prevent incursions by militants, the army said on Thursday, despite opposition from Kabul.

Pakistan decided to fence and mine parts of its western border after accusations from US and Afghan officials that the Taliban militants were launching attacks from sanctuaries in Pakistan.

“We have completed 20km of fencing in North Waziristan region and work is going on for the rest,” military spokesman Maj-Gen Waheed Arshad told Reuters.

He said the plan involved fencing a 35-km stretch in the northwestern tribal belt bordering Afghanistan in the first phase.

Afghanistan opposes fencing because of a long-standing territorial dispute, saying it would penalise Pashtun tribal communities living on both sides of the frontier, or Durand Line, named after the 19th Century colonial administrator who drew the border.Last month, Pakistani and Afghan troops clashed on the border in South Waziristan after Kabul said its forces tore down a Pakistani fence.

Pakistan confirmed the clash but denied it was erecting fence there.

Authorities have held off plans to mine the border.
