Explosions seen across the border as North Korea blows up roads linking it to South Korea

North Korea has destroyed roads and railways leading to the border with South Korea, highlighting its lack of interest in any chance of reunification.

South Korea denounced the incident, expressing disapproval that its neighboring country was "continuously engaging in such backward actions."

According to South Korea's military, around noon on Tuesday, sections of railway and roads linking the two countries were damaged.

This development followed increasing strain on the peninsula, as North Korea announced last week its decision to sever the connection routes and strengthen its positions along the border.

In reaction to the explosions, the South Korean military discharged warning shots.

A video shared by the military displays a cloud of smoke billowing up from a road in the northern region after an explosion occurred.

Sabotaging the roads aligns with Kim Jong Un's efforts to sever connections with South Korea and officially designate it as the North's main adversary.

This follows allegations from the North, which claimed that the South has sent drones over its capital three times this month to distribute propaganda leaflets.

The military of the country issued a warning about a potential "catastrophe" should the drones be found again and stated that it has positioned eight artillery units at the border, ready to engage if necessary.

Experts suggest that the North is very unlikely to carry out large-scale, pre-emptive strikes since its military capabilities are significantly outclassed by the forces of the US and South Korea working together.

South Korea has not confirmed if it deployed drones, but has indicated that it will take action against North Korea if the safety of its people is at risk.

Authorities in the South assert that since the beginning of this year, the North has been increasing its defenses by installing anti-tank barriers, laying mines, and strengthening roads along its border. This is likely a move to enhance its frontline security and deter both soldiers and civilians from defecting.
