The American-led U.N. command at the Demilitarized Zone dividing the two Koreas has dismissed as unsubstantiated accusations from North Korea that U.S. troops tried to provoke its frontline troops with "disgusting acts."

A North Korean military statement Friday warned U.S. soldiers to stop what it called "hooliganism" at the inter-Korean border village of Panmunjom or they'll meet a "dog's death any time and any place."

It said U.S. troops pointed their fingers at North Korean soldiers and made strange noises and unspecified "disgusting" facial expressions.

Saturday's statement from Christopher Bush, a spokesman for the U.N. command, says they looked into the allegations and determined they were unsubstantiated. (AP)
