Shops, restaurants and schools have shut in Moscow in a partial lockdown, as Russia battles record Covid deaths and infections.
Only essential shops like supermarkets and pharmacies are allowed to open in the capital, while food outlets are only providing takeaways.
Russia has reported a record 1,159 deaths from Covid in the past 24 hours.
The official data also reveals 40,096 new infections in 85 regions of Russia - another record.
Russia's overall Covid death toll in the pandemic is officially more than 230,000, the highest in Europe and one of the highest in the world. Russia's last major lockdown was in May-June 2020.
The proportion of Russia's population fully vaccinated remains low - on 23 October it was 32.8%, Our World in Data reports. Most European countries have much higher rates.
Despite an intensive state vaccination drive, many Russians remain suspicious of the Sputnik V vaccine, which is internationally recognised as an effective shield against Covid.
The Russian news service Vesti reports some panic-buying because of the new restrictions. There has been a rush on meat and fish at the central market in Orenburg, a city in the Urals east of Moscow.
