Officially the total of new coronavirus infections in Russia has overtaken the totals for China and Iran.

On Tuesday the Russian government reported a record daily rise in new cases – 6,411 – bringing the total to 93,558. Moscow has the most cases, compared with other Russian regions.

The number of deaths rose to 867.

Deaths are still far below those for the worst-hit countries, such as the US and Italy, but Russia’s numbers are rising daily.

Some medics do not believe the official data and are naming fellow medics they say have died from Covid-19. The list – 72 names so far – is posted on Facebook by Dr Vladimir Budiansky.

And an opposition website, Open Media, reports that dozens of nurses have quit a Moscow hospital – Kommunarka – where allegedly they were underpaid and lacking necessary protective kit. The management disputes their claims.
