At least 13 people have died from the massive gas leak at a chemical plant in southern India, with 800 others taken to hospital.
The leak from the LG Polymers plant in the city of Visakhapatnam in Andhra Pradesh state came as people slept.
Doctors say patients have been complaining of a burning sensation in the eyes and difficulties breathing.
Areas around the plant have been evacuated. The leak may have been due to negligence, officials say.
Reports suggest initial attempts to control the gas leak were unsuccessful but the company and state officials say the situation is now under control.
LG said in a statement it was investigating the cause of the incident, and was looking at ways “to provide speedy treatment” for those affected.
Rajendra Reddy, a senior official in the Andhra Pradesh Pollution Control Board, told the BBC that the leaked gas was styrene, which is usually refrigerated.
Prime Minister Narendra Modi called an emergency disaster meeting.

The leak took place at around 03:00 local time (21:30 GMT Wednesday) as the plant was being re-opened for the first time since 24 March, when India went into lockdown to curb the spread of coronavirus.
“All those who have been hospitalised are currently stable,” BK Naik, a local health official, told Reuters news agency.
Doctors say 86 patients are being treated on ventilators, but many injured have been discharged.
Legal action is being taken against the company, says state Industries Minister Goutam Reddy. Earlier, he told BBC that it looked as though proper procedures and guidelines were not followed when the South Korean-owned plant was being re-opened.
“We would like the company to proactively respond to the incident and ensure that the same level of responsibility is taken if this incident were to happen in EU or United States,” he said, adding that the incident had been reported to the Korean embassy.
Swaroop Rani, a senior police official in Visakhapatnam, told AFP that the plant had been left idle because of the lockdown.
“[The gas] was left there because of the lockdown. It led to a chemical reaction and heat was produced inside the tanks, and the gas leaked because of that.”
Local villagers complained around 03:30 and police immediately went to the scene, but had to quickly retreat for fear of being poisoned, the news agency quoted her as saying.
“One could feel the gas in the air and it was not possible for any of us to stay there for more than a few minutes,” she said.
