NEW DELHI: A toxic haze enveloped India’s national capital on Wednesday (Nov 13) morning as temperatures dropped and pollution surged, reducing visibility in some parts and prompting a warning from airport authorities that flights may be affected.
Delhi overtook Pakistan’s Lahore as the world’s most polluted city in Swiss group IQAir’s live rankings, with an air quality index (AQI) score of more than 1,000, considered “hazardous”, but India’s pollution authority said the AQI was around 350.
Officials were not immediately available to explain the variation.
The India Meteorological Department (IMD) said the pollution had reduced visibility to 100m in some places by around 8am.
“Low visibility procedures” were initiated at the city’s Indira Gandhi International Airport, operator Delhi International Airport Limited said in a post on social media platform X.
“While landing and takeoffs continue at Delhi Airport, flights that are not CAT III compliant may get affected,” the authority said.
CAT III is a navigation system that enables aircraft to land even when visibility is low.
