A three-month-old baby was among eight people killed in a fire at a Mumbai hospital, officials have said, in the latest disaster to highlight lax safety standards in India.

The blaze broke out around 4pm local time yesterday on the fourth floor of a government-run hospital in the northern suburb of Andheri.

The death toll rose from six to eight today, a spokesman for the city's disaster management cell told AFP.

Another 140 people, including patients, doctors and nurses were rescued and were being treated at hospitals across the city, he said.

The cause of the blaze at the ESIC Kamgar hospital is not yet known, but a fire official told AFP that the hospital had not sought a proper safety inspection.

"It is a 1970s building and no fire safety audit had been carried out," said MD Ogle, deputy chief fire officer at the Maharashtra Industrial Development Corporation, a state government agency.

"It is up to the occupier to seek an inspection."

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

They are particularly common in densely populated Mumbai, India's financial capital.

In December last year, at least 14 people were killed when a huge blaze tore through a popular restaurant in the city.

Earlier that month, a fire swept through a Mumbai sweet shop, sparking a building collapse that killed 12 sleeping workers.
