Seoul: North Korea accused the United States on Monday of bringing "heavy weapons" into the border truce village of Panmunjom and warned of strong military countermeasures unless they are withdrawn.
The North`s military mission at the village said US and South Korean forces introduced the weapons early Saturday but gave no details.
"The introduction of heavy weapons to the area around the conference hall where armed forces of both sides stand in acute confrontation is a premeditated provocation aimed to spark off a serious military conflict," the official news agency quoted the military as saying in a protest message to US forces.
The North threatened "strong military countermeasures" in the area, a top tourist venue for visitors to South Korea, unless the weapons are withdrawn.
Panmunjom, inside the Demilitarised Zone that bisects the peninsula, is the venue for sporadic meetings between the militaries of the two sides.
Under the armistice deal that ended the 1950-53 war, heavy weapons are banned in the village.
"The US imperialists and the South Korean puppet forces should never forget their bitter defeat six decades ago," the North`s military said, referring to its contention that it won the war.
A spokesman for the US military, which stations 28,500 troops in South Korea, said he was checking the report.
