Keeping in view the increasing level of pollution in Delhi and NCR, the apex court banned sale of firecrackers and said, we would ascertain after Diwali what is the difference and is there any decrease in pollution level. Certain traders of firecrackers with valid licences had knocked the doors of the apex court seeking its direction to modify its earlier order which had put a ban on firecrackers sale. The ban on sale would continue till further hearing in the case. (UNI)
