Pakistan security forces on Friday destroyed a radio tower near the Pak-Afghan border, security sources said.

"The Umar FM Radio Tower was destroyed along the Pak-Afghan border by security forces," sources told DawnNews.

They added that the move would stop the transmission of "hostile, anti-state propaganda".

The Pakistan Army has been taking measures to secure the country's border with Afghanistan in an effort to prevent cross-border terror attacks.

In December, it was reported that the Pakistan military has been pressing ahead with its plan to completely fence the 1,500-kilometre-long portion of the Pak-Afghan border billed as one of the most porous and perilous border regions in the world.

Thousands of soldiers and hundreds of vehicles are deployed at 14 different sites on a daily basis to undertake the arduous task of fencing the Pak-Afghan border — from Chitral to South Waziristan — putting in 7,000 man-hours for the installation of fabricated material.

The first phase of the project is likely to be completed by the end of 2018, which will see the fencing of 432km at the most critical points along the border.
