At least 22 patients died have died in a western Indian hospital after their oxygen supply was interrupted by a leak in a supply tank. The leak was plugged by the fire service within 15 minutes, but there was supply disruption in the Zakir Hussain Hospital in Nashik, a city in Maharashtra state, that is the worst-hit by the latest surge in coronavirus cases in India. Television showed images of people with empty oxygen cylinders crowding refilling facilities as they scrambled to save stricken relatives in hospital.
