Afghanistan–Pakistan border barrier

The Afghanistan–Pakistan border barrier refers to the border barrier being built by Pakistan since March 2017 along its border with Afghanistan. The purpose of the barrier is to prevent terrorism, arms, and drug trafficking, as well as refugees, illegal immigration, smuggling and infiltration across the approximately 2,670-kilometre-long (1,660 mi) international border between Afghanistan and Pakistan.

The Afghanistan–Pakistan border is marked by eight official crossing points and nearly 1,000 military forts. In addition to these forts, the Pakistan side of the border is also dotted with more than 1,200 border posts. There are over 400 forts in the northwestern area alone, complete with cameras and watchtowers, while more than 800 drones assisting the barrier. The Balochistan portion of the border is marked with roughly 600 forts . Before the 2021 Taliban capture of Afghanistan, the barrier and other measures were designed to impede the Afghan Taliban and Pakistani Taliban from freely crossing the border to coordinate and launch attacks against the governments of Afghanistan and Pakistan and evade authorities on either side. Despite the two Taliban organizations claiming to be completely separate from each other, Afghan Taliban leaders had been found operating from Afghan refugee camps in Pakistan and Pakistani Taliban leaders have been found hiding from Pakistani law enforcement in Taliban-controlled Afghanistan while systemically coordinating a joint militant network with their Afghan counterparts.
