The North Korean embassy in Russia is under suspicion of hosting a casino in one of its office buildings.
Russian newspaper "Izvestia" reported Thursday, that the Moscow-based embassies of North Korea and Belarus are operating underground casinos.
A local police investigation has found that the North Korean embassy leased a building last September, to use as a cafeteria, but instead ran it as a casino from December.
Only those who have made prior arrangements are allowed to enter the building.
Russia enacted a federal law to ban gambling in July 2009, and foreign embassies have been preferred venue for casinos, as they are immune from jurisdiction.
North Korea and Belarus have denied the allegations, saying that none of their embassies are used as gambling establishments.
