Sirsa had earlier blamed the AAP government in Punjab for stubble burning incidents contributing to pollution in the national capital.Delhi's air quality was in the 'very poor' category on Wednesday, with the AQI recorded at 379, according to the CPCB.There was no immediate response from the Delhi government or the BJP over the allegations.
