BENGALURU: Delhi ⁠was the world's most polluted major city on Saturday ​morning, according ​to Swiss group IQAir's live ranking, as the Indian capital faced severe pollution forecasts a day before Diwali, the Hindu festival of lights.

* India has ordered schools in and ⁠around Delhi to offer online classes and encouraged ⁠people to work from home ahead of Diwali on Sunday, which is usually marked by the widespread ‌use of firecrackers that further worsen ​the air ⁠quality.

* IQAir ranked Delhi first among ​the world's major cities ‌at 10:35 a.m. (0505 GMT), with a US air quality index ​reading of 581, double that of Lahore in neighbouring Pakistan, at 285.

* IQAir's reading, based on concentrations of air pollutants, is not directly comparable to India's ‌official index, which uses a different scale and ​methodology.
