Over the years, Pakistani authorities have grown increasingly concerned about the security situation on its borders with both Afghanistan and Iran. The border with Afghanistan, in particular, has been loosely governed and porous from day one. This is why Pakistani authorities have now commenced fencing its border with Afghanistan, in a bid to stop militants and drug traffickers from pouring into Pakistan.
This development is opposed by not only Afghan authorities but also by the Afghan Taliban. In recent months, when Pakistani security forces were stationed in Bramcha to fence off the border with Afghanistan, the Afghan Taliban blocked the effort in some areas.
Yeah, the drug dealers like their cash flow.
