At least 22 Covid-19 patients on ventilator at a government hospital in the western Indian state of Maharashtra died on Wednesday after their oxygen supply ran out following leakage of the life-supporting gas from a tanker, officials said. The tanker was brought to Zakir Hussain Municipal Hospital in the state's Nashik district to replenish the oxygen cylinders at the medical facility for continuous supply to the 150-plus Covid-19 patients on life support. "As per current information, 22 people have died due to interrupted supply of oxygen at Zakir Hussain Municipal Hospital in Nashik," district collector Suraj Mandhare told the media. Local TV channels aired footage of oxygen leaking from the tanker stationed outside the hospital and firefighters trying their best to stop the leak by spraying water.
