Delhi Deputy Chief Minister Manish Sisodia said that the Delhi government would take a final decision on the closure of schools and introduction of the odd-even car rationing scheme after examining a report from environment department. He has directed the environment department to submit a report on the city's pollution level by this evening. Delhi woke up to 'severe' air quality today under a blanket of thick haze, as pollution levels breached the permissible standards by multiple times.
