The Durand Line serves as the  de facto border between the two countries.

The residents even claimed that most of the encroachments have occurred in the Khas Kunar and Sarkano districts of Kunar.

The residents of the two districts said that in some areas the Pakistani forces have built fences along the line, reports Tolo News.

“They (Pakistani forces) entered on our soli and built their installations and fences under the pretext of building joint bases here for Afghan, US and Pakistani forces to chase enemies and conduct joint operations against them,”  Din Mohammad Safi, a member of Kunar's provincial council, told the news portal based in Afghanistan.

Nawa village in Sarkano district is one of the areas, according to residents, where Pakistani forces have advanced towards the Afghan side of the Durand Line, reported the news portal.

The residents of the regions told Tolo News about 10 parts in Sarkano district where, according to them, Pakistani forces have built fences, leaving families stranded on the two sides of the line.

Abdul Wadood, a resident of Sarkano district,  told the news portal: "My uncles are here. We used to meet each other before the fence was built, but after that we haven’t met since."

Documents show that a delegation from military and civilian institutions in a 2016 paper reported the advancement of Pakistani forces along the Durand Line, reported the news portal.
