This is a developing story.

At least seven people were killed and 25 injured because of a fire that broke out in a high-rise apartment building in India's Mumbai Saturday evening. Fifteen fire engines were eventually able to douse the blaze at the 21-story complex in the Chandivali area of the city, the Times of India reported.

The injured reportedly were taken to the Hiranandani Hospital, where the conditions of two of them were listed as serious, police said.

"An investigation is being conducted by the fire brigade. The fire was possibly a result of a short circuit that occurred in flat 1403 of the building," said Deputy Police Commissioner Vinayak Deshmukh, who noted a firefighter also was taken to the hospital after being overcome by smoke. 

The fire brigade reportedly said three people were found dead inside an elevator, apparently after having suffocated, and that several people are still trapped inside the building. The death toll is expected to rise, authorities said.

A report on the cause of the fire should be available Sunday.
