The restaurant was closed as a result of mass unscheduled inspections by Rospotrebnadzor, the regulator, a spokeswoman for McDonald's in Russia said.

The state watchdog agency previously closed three McDonald's restaurants in Moscow and one in Stavropol and unveiled sweeping checks at its outlets across the country.

Rospotrebnadzor was not immediately available for comment.
