As toxic haze and smog took the national capital in its grip and the air quality worsened alarmingly, the Delhi Government of Arvind Kejriwal decided to bring back the Odd-Even formula for vehicle owners in a last ditch effort to reduce vehicular congestion and pollution from November 13. 

The scheme, under which odd number vehicles ply on odd dates and even numbered on even dates, will be implemented for five days till November 17. 

For the past three days, citizens in Delhi are battling air pollution emergency with doctors declaring it to be a state of medical emergency and schools ordered shut till Sunday. The government has banned the entry of trucks and construction activity as public health crisis stared menacingly. 

Delhi Chief Minister Arvind Kejriwal urged Punjab and Haryana governments to desist their farmers from burning waste and crop stubble which added to air pollution.
