The latest move comes after Pyongyang accused South Korea of sending drones carrying propaganda leaflets into its capital.
South Korea’s military says North Korea has blown up the northern sections of roads connecting South Korea.
Parts of the road north of the military demarcation line that separates the countries were blown up around noon (03:00 GMT), joint commanders said in a statement to the media on Tuesday.
It said the army fired warning shots south of the LoC.
Seoul warned on Monday that Pyongyang was preparing to blow up roads.
Tensions have risen on the Korean peninsula, with North Korea accusing its neighbor of sending drones carrying propaganda leaflets into the country’s capital, Pyongyang.
The explosions came a day after North Korean leader Kim Jong Un discussed the issue with his top military and security officials.
During the meeting, Kim described the flights as a “serious provocation by the enemy” and laid out unspecified tasks related to “immediate military action” and his “war prevention” operation to protect the country’s sovereignty, North Korean state media reported earlier on Tuesday. .
North Korea has previously put advanced artillery and other military units on standby to launch strikes on South Korea if North Korean drones are spotted again over North Korea. South Korea has refused to confirm whether it has sent drones, but has warned that North Korea will be severely punished if the security of its citizens is threatened.
Demolition of roads would be appropriate Kim Jong Un’s abundance severing ties with South Korea, formally establishing it as his country’s arch-enemy, and abandoning North Korea’s decades-long pursuit of peaceful Korean unification.
In 2020, North Korea dismantled the inter-Korean liaison office, marking the end of the period of detente.
In November last year, Pyongyang said it would move more troops and military equipment across the border and no longer abide by the 2018 Joint Military Agreement after Seoul suspended parts of the accord in response to Pyongyang’s launch of a military spy satellite.
South Korean officials have said North Korea began adding anti-tank barriers along the border earlier this year and laying mines.
