Delhi's air quality remains severe, thick smog grapples the city

Delhi's air quality remained in the 'severe' category on Friday despite a slow but "significant" improvement in pollution levels with the AAP government restricting the entry of heavy and medium goods vehicles into the national capital as an emergency measure.
The Indian Institute of Tropical Meteorology (IITM) said stubble burning in neighbouring states on Thursday was the "largest-ever recorded" for this year with 2,,100 fire counts, which might lead to a further deterioration of the already "severe" air quality of the national capital.
