The main reason behind the oxygen shortage crisis in Delhi is the 'jungle raj' by the Haryana and Uttar Pradesh governments, said Deputy Chief Minister Manish Sisodia on Thursday, asking the Central government to intervene in the matter.

While addressing a press conference here, Sisodia alleged that despite the Centre's increased oxygen allocation to the national capital, government officials and Police of the two states were not allowing the oxygen supply to leave for Delhi.
