The latest capture of several areas, including Delhi, from news agency ANI's drone camera at 8 am, showed the severity of the pollution. Kartavya Path, ITO, Lodhi Road, Khan Market, and Prithviraj Marg depicted the area engulfed in a thin layer of haze. Water sprinklers were also used in the Lodhi Road area to curb pollution.
