NEW DELHI -- Twenty-two COVID-19 patients on ventilators died in a hospital in western India on Wednesday when their oxygen supply was interrupted by a leak in a supply line, officials said.
Suraj Mandhar, the district collector, said the supply of oxygen has since resumed to other patients.
Television images showed white fumes spreading in the hospital area, causing panic.
Surinder Sonone, a police officer, said the leak occurred in a pipe connecting the oxygen supply to the main tank in the hospital complex.
Five of the 140 COVID-19 patients were shifted to another hospital, he said.
The state government ordered an investigation of the leak, state Health Minister Rajesh Tope said.
India has reported a new record 295,041 coronavirus cases, as the daily death toll crossed 2,000 for the first time.
Even with hospitals struggling, Prime Minister Narendra Modi on Tuesday advised state governments against imposing a harsh lockdown in favor of micro-containment zones as he sought to avoid another economic slump.
Overall, India has reported more than 15.6 million confirmed cases, the second highest behind the United States. The number of deaths stood at 182,553.
