NEW DELHI, May 13 (Xinhua) -- At least 16 people were killed Friday in a devastating fire inside a commercial building in the Indian capital, officials said.

       The fire broke out at around 4:40 p.m. local time in the building located near the Mundka metro station in outer Delhi.

       "A total of 16 bodies were recovered from the three-storey commercial building which had caught fire this evening near Delhi's Mundka metro station," Atul Garg, director of the Delhi fire service, told local media.

       According to Garg, the third floor of the building was yet to be searched.
