At least 22 COVID-19 patients on ventilator support suffocated to death on Wednesday when their oxygen supply stopped suddenly because of a malfunction in the main storage of the civic-run hospital in Nashik, officials said. 

"I am deeply distressed by the unfortunate incident of patients dying due to gas leaks in a hospital's oxygen tank in Nashik, Maharashtra. My deepest condolences to the families who lost their loved ones in this accident. I wish all other patients a quick recovery," Kovind said in a tweet in Hindi.
