South Korean probe concludes Pyongyang planted DMZ mines

South Korean and UN investigators have concluded that two landmines that exploded inside the Demilitarised Zone (DMZ) last month and injured three soldiers had been planted by North Korea, Seoul's military said on Monday.



The findings by the military and the US-led United Nations Command were consistent with a preliminary probe that indicated North Korean troops had crossed the Military Demarcation Line - an accusation Pyongyang denies.



The DMZ, one of the world's most heavily fortified and mined frontiers, has divided the Korean Peninsula since the 1953 armistice.



Landmine incidents have previously heightened tensions between the two Koreas, which remain technically at war.



"Given the significance of the incident, the National Forensic Service conducted several rounds of forensic analysis," Kwon Dae-won, vice chairman of South Korea's Joint Chiefs of Staff, said at a briefing to present the findings.
