Some 489 medics have died in Russia after contracting coronavirus, the country's health watchdog, Roszdravnadzor, has said.

The latest toll is a sharp rise from the 101 reported last month.

Roszdravnadzor chief Alla Samoilova said problems in supplying protective equipment had been a contributing factor.

"If I'm being honest, there were issues at the start, there were some shortcomings," she said.

With more than 561,000 cases - including 7,790 during the last 24 hours - Russia has the third-highest number of cases globally. Its official death toll stands at 7,760.
