Two Indian cities, Kolkata and Mumbai, joined New Delhi as some of the world's most polluted cities following Diwali celebrations. New Delhi claimed the top spot with an air quality index (AQI) of 420, categorized as 'hazardous.' Kolkata ranked fourth with an AQI of 196, and Mumbai stood at eighth with an AQI of 163.
