Fire on Saturday gutted a Moscow hospital treating patients infected with coronavirus, killing one.

According to Daily Mail, hospital officials said the inferno started from a patient’s room, adding that the fire has since been put out.

Sergei Sobyanin, the Mayor of Moscow, who confirmed the development on Twitter, said that all patients had been evacuated and would be transferred to other hospitals.

“The causes of this incident will be thoroughly investigated,’’ Sobyanin added.

COVID-19 has so far infected nearly 200,000 people and caused more than 1,800 deaths in Russia.

More than half of the country’s cases and deaths have been recorded in Moscow, a sprawling city of 12.7 million.
