Pyongyang has alleged that American personnel were pointing their fingers at North Korean , making strange noises, and pulling “disgusting” facial expressions.
In a statement, the secretive state’s warned US to end the “hooliganism” at the village which divides North and South Korea, or else they would meet a “dog’s death any time and any place”.
It was also claimed that US had encouraged fully armed South Korean to aim at their adversaries, which North Korea described as a “dangerous provocation”.
Christopher Bush, a spokesman for the UN command in the region, said the allegations were investigated but determined to be unfounded.
This is not the first time that North Korea has accused South Korean and US of trying to wind up its forces, and vice versa.
After Pyongyang conducted its first nuclear bomb test a decade ago, American claimed that North Korean were spitting across the demarcation line, flashing their middle fingers, and making throat-slashing gestures.
There are currently about 28,000 US deployed in South Korea in a bid to deter potential aggression from across the border.
The latest spat unfolded in Panmunjom, where an armistice heralding the end of the Korean War in 1953 was signed.
Despite being one of the world’s most dangerous flashpoints, the village is popular with tourists – but guides regularly warn visitors against making gestures which could antagonise the North Korean nearby.
