Russian news agencies are reporting that the country's food safety agency will conduct checks on McDonald's restaurants in the Urals after safety complaints, a day after four branches of the chain were shuttered in Moscow.

Natalya Lukyantseva, an official in the Sverdlovsk regional office of the agency, told RIA Novosti and Interfax on Thursday that unplanned checks were being conducted in a number of restaurants after residents voiced safety concerns. The inspections come one day after the agency, known in Russian as Rospotrebnadzor, ordered four Moscow-based restaurants to suspend operations because of sanitary law breaches.

One of those restaurants, on Moscow's central Pushkin Square, became a symbol of reform in the Soviet Union when it opened in 1990, drawing crowds of thousands.
