At least 10 people have died after a massive fire broke out at a hotel that was being used as a Covid-19 facility in India's southern Andhra Pradesh state early this morning, police said.

"Several people who were trapped and injured have been rescued and moved to a government hospital," one constable at the police control room said.

"Fire is under control but rescue and firefighting operations are still under way," he added.

Initial reports suggest the fire was caused by a shortcircuit in the centre, officials said.

Indian Prime Minister Narendra Modi said he was "anguished" by the fire.

Home Minister Amit Shah tweeted: "Deeply anguished by the news of tragic fire accident at a Covid-19 facility in Vijayawada, Andhra Pradesh".

"Centre assures all possible support to the state government. My condolences are with the affected families in this time of grief.

"Praying for the speedy recovery of those injured," he wrote.

Chief Minister of Andhra Pradesh Jagan Mohan Reddy has instructed officials to conduct an inquiry into the hotel fire.

"The incident took place around 5am. Around 22 patients are being treated in the hospital. We are evacuating the entire building," Mohammad Imtiaz, Krishna's district collector, was quoted as saying.

Last week, eight Covid-19 patients died in a fire that broke out in the intensive care ward of a private hospital in India's western city of Ahmedabad.

India has over 2.1 million confirmed cases of Covid-19, which is the third highest number in the world.

More than 43,000 people who had contracted the virus there have died.
