Delhiites woke up on Thursday to a thick envelope of smog as air quality in the national capital and in adjoining regions, dipped into severe category again.
The UN health agency says nearly everybody in the world breathes air that doesn’t meet its standards for air quality, calling for more action to reduce fossil-fuel use.
Pakistan's Lahore has been declared the most polluted city globally after the city recorded its highest ever smog levels as the Air Quality Index (AQI) went above 700, reported a local media.
Air pollution has been reduced to some extent due to rainfall occurred in the hilly areas of the country including Kathmandu Valley on Wednesday evening.
