Amid alarmingly high pollution levels in Delhi, Environment Minister Gopal Rai on Tuesday urged the Centre to convene an emergency meeting to tackle the issue and said it is the moral responsibility of Prime Minister Narendra Modi to intervene in the matter.

The air quality in the national capital has remained in the “hazardous” category since Sunday, with AQI readings consistently above 450. Rai said the Centre has not acted on the Delhi government's repeated requests to allow artificial rain in the national capital and he will again write to Union Environment Minister Bhupender Yadav.
