The Supreme Court on Monday had sharp words for Delhi Police and demanded "immediate action" to stop the sale and bursting of firecrackers in the city - an annual activity that defies an existing ban - even days after Diwali, observing sharply that "no religion encourages pollution". "No religion encourages any activity which creates pollution. If firecrackers are burst in this fashion... it also affects fundamental right to health of the citizens," a bench of Justice Abhay S Oka and Justice Augustine George Masih, hearing a case on Delhi's yearly air quality crisis, said.
