Pakistan has started sealing its long border with Afghanistan and areas vulnerable to cross-border militant attacks.
Pakistan and Afghanistan share a nearly 2,600 kilometer, largely porous, border and both blame each other for encouraging terrorist infiltration to support deadly attacks on their respective soils.
Mohmand and neighboring Bajaur district has been identified as “high threat zones”.
Relations between the countries have nosedived in the last two years over mutual terrorism allegations.
Pakistan closed all border crossings with Afghanistan a month ago, saying terrorist attacks in Pakistan were being orchestrated by fugitive anti-state militants sheltering in Afghan border areas.
Pakistan reopened the crossings this month to allow legal travelers and thousands of stranded Afghanistan-bound shipping containers to resume their journey.
Afghanistan has however rejected the charges leveled by Pakistan. Instead it demanded Pakistan to close insurgent sanctuaries on its side of the border being used to fuel violence in Afghanistan.
