The odd-even rule will be back in Delhi the day after Diwali and schools closures has been extended up to Class 11 in view of the rising pollution levels, State Environment Minister Gopal Rai said today. All schools will be shut across the national capital except Classes 10 and 12 till November 10, the minister said. Currently, only classes up to Class 5 are suspended in view of the deteriorating air quality. The odd-even rule, which has been the Arvind Kejriwal government's flagship move in fighting pollution for the past few years, will be back for a week on November 13, the day after Diwali.
