North Korea is reportedly building a wall to fully close off one of the two inter-Korean roads it blew up earlier this month, amid heightened cross-border tensions.

According to the Voice of America on Friday, satellite imagery taken by Planet Labs the previous day shows a structure that appears to be a wall on the Gyeongui Line road, which used to connect Paju in South Korea and the inter-Korean Gaesong Industrial Complex in the North. 

The structure was estimated to be approximately 95 meters long. 

Satellite imagery also showed a 200-meter-long barrier on the Donghae Line road, where barrier installation work was recently captured by South Korean military surveillance assets.

North Korea blew up sections of the two inter-Korean roads on October 15. 

The walls are believed to be there to prevent the movement of tanks and the defection of North Korean soldiers and residents.
