Russia is facing an increase in cases of coronavirus and thus deaths.
The country, which reported 752 coronavirus-related deaths on Saturday, is the most confirmed in a single day since the pandemic began.
It pushes the national death toll to over 142 thousand.
Coronavirus task force also reported over 25 thousand new cases of coronavirus, including over 5 thousand in Moscow alone.
Authorities are struggling to suppress an increase in infections caused by the more contagious Delta variant.
Officials have also been trying to encourage Russians to get vaccinated since infections began to rise sharply last month.
Demand for vaccination has been slow, but authorities say it is picking up significantly.
The health minister said nearly 30 million people had received the first dose of a coronavirus vaccine.
In Moscow, residents have to show a QR code proving that they have had a vaccine, a negative test or immunity to be able to sit inside cafes or bars.
A state communications authority said it had blocked 399 websites containing information about the sale of fake vaccination certificates and QR codes.
