North Korea is building an unidentified structure on the inter-Korean road.

North Korea blew up sections of the eastern Donghae and western Gyeongui roads north of the Military Demarcation Line separating the two countries on October 15. The move came days after Pyongyang said it would cut all road and rail links to South Korea and build frontline defense structures.

Since the explosion, South Korean border monitoring sources have detected that North Korea has leveled the ground on the two disconnected roads, according to military sources. The sources also said that North Korea has recently built facilities on the Donghae line.

According to Yonhap news agency, these structures could be concrete border fence frames.

The source said the military has yet to detect any signs of North Korea building such structures on the Gyeongui route.

This month's explosions marked the complete destruction of inter-Korean land routes - once seen as symbols of reconciliation and cooperation between the two Koreas.

Pyongyang first mentioned cutting off inter-Korean road and rail links after joint military exercises between the US and South Korea a few weeks ago. North Korea called the move provocative war exercises for aggression. Since then, the North Korean military has fortified the border with frontline artillery, army units, mines and barricades.

North Korea scrapped the goal of unification after leader Kim Jong-un identified the two Koreas as “enemy states” late last year, saying there was no point in seeking reconciliation and unification with South Korea.

On October 17, the North Korean Constitution officially designated South Korea as a “hostile state” for the first time. This development came after a meeting of the Supreme People’s Assembly of North Korea the previous week, which was believed to be aimed at amending the country’s key laws.

Pyongyang also declared that North Korea's border with "hostile country" South Korea would become an eternal fortress.

Tensions between North and South Korea have escalated since 2023, when both sides declared a 2018 agreement to ease military tensions no longer valid.

In recent days, North Korea has accused South Korea of ​​sending drones into its airspace and vowed to retaliate. South Korea has neither denied nor confirmed that it was behind the incident.
