WATCH: Smog blankets New Delhi after Diwali celebrations

New Delhi was blanketed by smog on Monday after a weekend of Diwali celebrations, PBS NewsHour reported. Air-quality monitors recorded hazardous pollution levels that pose health risks to nearly everyone. Seasonal conditions, including cooler weather and low winds, trap vehicle emissions near the ground, while crop burning in neighboring states also contributes. India’s Supreme Court had allowed limited use of green firecrackers during the holiday.
