At least 27 people died and dozens more were injured in a massive fire in a building in the Indian capital New Delhi on Friday, emergency services said.

"The fire has been put out now. The total number of dead is 27. Search operation is on," a fire department official told AFP.
Broadcaster NDTV reported that more than 40 people had sustained burns and were hospitalized.

The large fire broke out at a four-storey commercial building in west Delhi in the late afternoon, but its cause was not immediately clear.

The third floor of the building had not yet been searched and more dead bodies were expected to be recovered, TV channel CNN-News18 quoted Atul Garg from the Delhi fire service as saying.

Sunil Choudhary, deputy chief fire officer from the Delhi fire service, put the death toll at a slightly lower 26.

"More than 25 people are injured, including those who jumped from the building," Choudhary told AFP.

Around 60 to 70 people have been rescued from the building, local media quoted police as saying.

The blaze started from the first floor of the building, which houses the office of a security camera and router manufacturing company, NDTV quoted police official Sameer Sharma as saying.

More than 30 fire trucks were still at the spot along with ambulances.
