North Korea blew up roads connected to South Korea on Tuesday, according to the Joint Chiefs of Staff (JCS). In its message to reporters, the JCS said that the North “detonated roads connecting the Gyeongui and Donghae rail lines north of the military demarcation line (MDL) around noon.

North Korea blew up sections of roads in its own territory that are part of links once used to connect the southern part of the peninsula with the north, in a show of defiance after it accused Seoul of flying drones over Pyongyang.

In a move that underlines North Korea's growing anger with South Korea, North Korea has blown up sections of unused rail routes and roads that once connected the two countries.
