Story summary
On September 21, two explosions near the Demilitarized Zone (DMZ) injured three South Korean soldiers. The South Korean Joint Chiefs of Staff suspect North Korean landmines were responsible and claim this violates the 1953 armistice agreement ending the Korean War. In response, South Korea’s Defense Minister Kang Shin-chul warned of "corresponding measures" if confirmed.
North Korea denies responsibility, with leader Kim Jong Un's sister, Kim Yo-jong, accusing South Korea of fabricating claims to escalate tensions and threatening retaliation if Seoul attacks North Korean border workers. The incident raises concerns over military communication channels between the Koreas, which are already limited, potentially leading to further conflict amid ongoing nuclear developments in North Korea.
The US-led United Nations Command also confirmed that North Korea violated the armistice agreement by placing mines on South Korea's side of the DMZ. This has heightened regional tensions and prompted demands for an apology from Pyongyang.

The US-led UN command (UNC), which oversees the 1953 armistice that halted but did not end the Korean war, said on Wednesday that a joint investigation with South Korea’s military had identified a live North Korean anti-personnel mine on the southern side of the military demarcation line (MDL), the de facto border.
