Delhi air quality worsens ahead of Diwali
On Wednesday morning, Delhi's AQI stood at 377.
Experts attributed the sudden deterioration in Delhi's air quality to falling temperatures, slow winds and an increase in crop-residue burning in Punjab and Haryana.
Delhi recorded its lowest average AQI for October in eight years before the sharp rise in pollution.
