Russian officials have released rare footage showing North Korean laborers at a construction site in Vladivostok in apparent violation of U.N. sanctions, part of an effort aimed at quashing rumors about dog meat consumption.

Vladivostok authorities filmed what appear to be several DPRK workers during a visit to the construction site of Samolet, one of Russia’s largest real estate developers, in early April.

In a video posted by the Vladivostok Municipal Coordination Center, a city official responds to reports that North Koreans mistreat dogs and even use them for food, stating on camera that “Koreans legally work here”
