Russia reported 8,706 new coronavirus cases on Saturday, raising its cumulative tally above 520,000 as data showed that more than 2,700 people infected with the virus had died in April.
With 520,129 cases, Russia has the third-highest number in the world after the United States and Brazil. Its official death toll stands at 6,829, many times lower than the figure seen in other countries with serious outbreaks.
The Kremlin has denied any problem with its official data after the World Health Organization (WHO) said Russia's low death rate was "difficult to understand."
Rosstat, the country's state statistics service, on Saturday published data showing that 2,712 people infected with the coronavirus had died in April. The virus was identified as the main cause of death in 1,660 cases, the data showed.
