MUMBAI - At least 15 people were killed when a huge blaze tore through a popular restaurant in Mumbai early on Friday, police said, in the latest disaster to raise concerns over fire safety in India.

Many of the victims were young women who were attending a birthday party on the rooftop when the fire broke out. Doctors said they died of asphyxiation, apparently as they tried to flee the burning building.

Television footage of the latest disaster showed fire engines and emergency teams rushing to the scene as the building in the city's Kamala Mills compound was being consumed by flames and dark plumes of smoke rose into the night sky.

The restaurant was which also houses hotels and offices.

Local media reported that a false ceiling had collapsed in the four-story building in the Indian financial capital, trapping people inside as they tried to escape.

The fire was extinguished in the early hours but a reporter at the scene said the rooftop where the party was taking place had been gutted, with charred ice buckets and ashtrays strewed around.

More than 50 people were brought to a hospital, of whom 12 were being treated for injuries that were not life threatening, said Avinash Supe, a doctor at KEM Hospital.

Police said they were investigating the cause of the fire, and had filed a preliminary case against the restaurant's owners.

Eleven of the victims were female partygoers, according to authorities.

One woman who said she was in the building at the time told of the desperate scenes as people tried to escape.

"There was a stampede and someone pushed me," Sulbha Arora said on Twitter.

"People were running over me even as the ceiling above me was collapsing in flames. I still don't know how I got out alive. Some powers were definitely protecting me."

Babu Lal, who was celebrating his granddaughter's birthday at the restaurant, complained of poor safety standards at the crowded restaurant.

"I didn't see any fire extinguishers there," Lal said. His granddaughter died in the fire, he said.

Fatal fires are common across India because of poor safety standards and lax enforcement of existing regulations.

A fire swept through a sweet shop in Mumbai earlier this month, sparking a building collapse which killed 12 sleeping workers.

In September, a gas cylinder exploded in an unfinished building in Mumbai killing six people.

Such disasters are particularly common in Mumbai, where millions live in cramped, dilapidated properties because of high rental prices. Activists say builders and landlords often cut corners on safety to save costs.

India's Prime Minister Narendra Modi tweeted that he was "anguished by the fire in Mumbai".
