McDonald’s has been caught in the crossfire of growing hostilities between Russia, Ukraine and the West. The world’s largest fast-food chain said Friday that as many as 12 restaurants in Russia are currently shut down, including its flagship location in central Moscow. This comes after Russia’s regulator, Rospotrebnadzor, enforced closures over alleged safety and hygiene concerns. The regulator is also inspecting 100 more locations throughout Russia. Tensions have boiled after the U.S. and EU enacted sanctions against Russian products and companies in response to the country’s involvement in the Ukrainian conflict.
