The Supreme Court has expressed concern over the situation of pollution in the national capital on Diwali, saying that the ban on firecrackers was hardly implemented.
The apex court has asked the Delhi government and police about the steps taken to implement the orders completely banning the manufacture, sale and bursting of firecrackers in the national capital and the action they took against violators.
"We want the Delhi government to immediately respond as to why this has happened. We want all the orders to be placed on record banning the sale, manufacture and bursting of firecrackers in Delhi, the court said.
A meeting of all the departments concerned has been called by Environment Minister Gopal Rai on Tuesday to review the steps taken under the Delhi government's Winter Action Plan.
