Fencing
In September 2005, Pakistan stated it had plans to build a 2,400-kilometre (1,500 mi) fence along its border with Afghanistan to prevent insurgents and drug smugglers slipping between the two countries. Former Pakistani President Pervez Musharraf had subsequently offered to mine the border as well.
The plans to fence and mine the border were again considered in 2007 and then in 2009, but they were not fully implemented. However, a 35-kilometre-long (22 mi) portion along selected border areas was fenced and the work was discontinued for lack of funds. In June 2011, Major General Athar Abbas, the then spokesman for the army, said: "We did fence around 35km of the border area as it faced continuous militant incursions. It was a joint project of ISAF and Afghanistan. But then they backed out.
It was a very costly project." During the Musharraf period, a biometric system was installed by Pakistan on border crossings. Afghanistan had objected to the system. The bio-metric system remains intact at the border, although it is yet to be made fully functional.
