A group of North Korean workers in Russia clashed with their Russian counterparts at a shipyard in Vladivostok over construction materials, a US-based news media report said Tuesday.

According to Radio Free Asia, dozens of North Korean workers were seen engaging in a fight with Russian laborers in a video clip released by the Russia's Far East news portal Deita.

The 26-second video showed the North Koreans hurling abuses at the Russians with some strangling and kicking them. The incident occurred last Friday.

An official at the dockyard said the North Koreans employed by a local construction company clashed with Russian laborers when the latter attempted to move materials that were set aside days earlier.

"Such tussles occur from time to time," the official said. He claimed that North Koreans react very sensitively to others touching their stuff and even destroy structures built with their materials. (Yonhap)
