At least 16 people were injured when a fire broke out in a coach of the underground rapid transit system in the eastern Indian city of Kolkata on Thursday, officials said.

Smoke engulfed the first coach of a train on the Kolkata Metro while it was running between two stations, Metro spokeswoman Indrani Banerjee said.

‘The fire was put out by our staff using fire hydrants, the city fire service and police also reached the scene. All passengers have been safely evacuated from the train,’ Banerjee said.

One passenger suffered a fracture in the scramble following the fire.

Fifteen others - mostly elderly people - were being treated for smoke inhalation-related injuries, senior city police official Aparajita Rai said.
