Delhi CM Arvind Kejriwal has requested all states to provide medical oxygen and oxygen cylinders to the national capital. Hospitals in Delhi are turning back Covid-19 patients owing to the shortage of medical oxygen. <br /> <br />Responding to the Delhi government's statements, Union Health Minister Dr Harsh Vardhan told media outlets on Saturday, "Delhi has been allotted more than the quota [oxygen] they had asked for, and Delhi CM even thanked the PM for that yesterday. Now, to rationalise the quota in a timely manner and the responsibility to finely plan it lies with the state government."
