The Supreme Court on Saturday suggested the Centre for a two days lockdown to tackle air pollution in the national capital.

A Bench of Chief Justice of India NV Raman, Justices DY Chandrachud and Surya Kant said, "Tell us how we can reduce AQI from 500 at least by 200 points. Take some urgent measures. Can you think of two days lockdown or something? How can people live?"The Apex Court said that air quality in Delhi is in the 'severe' category and in another two to three days it will dip further.
