Eleven people died in India after a leak of gas.
The leak occurred in an industrial zone in the city Ludhiana in Punjab state.
Rajinder Pal Kaur Chhina is a member of Ludhiana’s legislative assembly. She said that at least nine other people were also taken to the hospital.
She added that a team from the National Disaster Response Force, along with a group of experts, had been sent to the scene to determine the source and cause of the leak.
Residents have been evacuated from the densely populated region.
“The incident occurred near a dairy and a doctors’ clinic, although we can’t say with certainty where the leak started,” Ms Chhina said to Reuters.
The people who went to the store in the morning to buy milk fell unconscious outside.
Anjan Kumar, a local resident, said that three of the bodies “turned blue” in a video posted by ANI on Twitter.
Surabhi Malik of the Press Trust of India told the news agency that it is possible that the gas could have been spread by manholes.
We will collect samples from the manholes. She said that it is likely that a chemical has reacted in manholes with methane.
Bhagwant Man, the chief minister of the state, tweeted: “All help is provided.”
