Islamabad, July 2 The Pakistan Army has 'reorganized' its troops along the Afghan border to prevent the spill over of militants from the neighboring country following the fresh US-Afghan onslaught on the Taliban today.

"We've mustered more troops from the other areas of the border to deploy opposite the Helmand region. It is sort of a reorganization," the ISPR spokesman Major General Athar Abbas said.

About 4000 US Marines and 650 Afghan troops have intensified their action against the militants in the Helmand province, supposedly a Taliban stronghold,The News reports.

US and Pakistan officials are concerned that their intense troop build-up in the region could see the militants cross over to Pakistan from Afghanistan through the poorly guarded porous mountain range.

The US believes that Taliban's top commanders are hiding in the region opposite Helmand, which is around 260 kilometers long. (ANI)
