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.
