Coronavirus: COVID-19 cases have been rising in Delhi New Delhi: The Arvind Kejriwal government is responsible for Delhi's current oxygen crisis in more ways than one, government sources have indicated. Pointing to the proposed oxygen plants in four hospitals that would be supported by the PM-Cares fund, sources said the Delhi government had not done its homework on these. Sources in the Railway Ministry also said that even now, the Delhi government has not provided cryogenic tankers for the 'Oxygen Express'. The Delhi government brushed it off as "outrightly false statements" given by the centre to "hide its abject failure in setting up of PSA oxygen plants in Delhi".
