The Delhi government has imposed a "perpetual ban" on the manufacture, use and sale of firecrackers, including through online platforms, in the national capital, according to an official order.

Principal Secretary (environment) of the Delhi government A K Singh invoked the "perpetual ban" on firecrackers under the Environment (Protection) Act, 1986. The ban covers the manufacturing, storage, and selling, including delivery through online marketing platforms, of all kinds of firecrackers and their bursting in Delhi, said the order.

The move comes amid Delhi facing hazardous air pollution levels leading to a range of restrictions including a ban on construction activities and entry of trucks in the city.
