At least 9 people died today in south India in a fire that broke out in a parked train car while a passenger was making tea, officials said.

The carriage, which was not attached to a train, was parked at Madurai Junction in the southern state of Tamil Nadu when the fire broke out before dawn today.

“It was an isolated carriage that was parked, which had been booked by a private tour operator. Someone tried to make a tea and that caused the fire,” said Sally Thalapathyrepresentative of Madurai district.

“Nine people died, including three women. Nine others were injured, but their lives are not in danger,” he added, clarifying that none of the dead have yet been identified.

According to local media, a gas cylinder had been illegally transported inside the carriage, which exploded.

India, which has one of the largest railway networks in the world, has experienced many disasters. The worst occurred in 1981 when a train derailed while crossing a bridge in state of Bihar and fell into a river, killing 800 people. In June, an accident involving three trains killed around 300 people in Odisha state.
