The national capital woke up to thick and heavy layer of smog on Tuesday, a day after Diwali festivities, as the air quality deteriorated to the ‘very poor’ category.
The Supreme Court had allowed the bursting of green firecrackers between 8 pm and 10 pm on the festival day. However, these rules were widely flouted, with firecrackers being used well outside the permitted windows.
