Moscow disinfected train stations amid rising COVID-19 cases in Russia.
Russia recorded 14,231 new COVID-19 cases on Wednesday, a record since the beginning of the pandemic.
It comes as President Vladimir Putin announced that Russia has approved its second coronavirus vaccine after early trials.
Russia has the fourth-highest virus caseload in the world with a total of 1.3 million registered infections, and more than 23,000 deaths.
The World Health Organisation said Tuesday there were more than 700,000 new COVID-19 cases reported in Europe last week, a jump of 34% from the previous week.
Britain, France, Russia and Spain accounted for more than half of the new infections.
