On Wednesday, Supreme Court slammed Punjab, Haryana and Delhi for failing to control air pollution in the national capital and other regions. The Apex court said, "We want immediate action to deal with stubble burning. It seems that there is no coordination among officers and the state government to deal with this situation.”
