Lahore, Pakistan, experienced record-breaking air pollution on November 2, with an Air Quality Index (AQI) of 1,900, six times higher than the World Health Organization's limit. The Pakistani government attributed the surge to winds carrying pollution from India and seasonal crop residue burning.

Not Delhi but Pakistan's Lahore has become the world's most polluted city with an Air Quality Index of 1,900 on Sunday, which is its highest ever.

In light of the worsening pollution crisis, Lahore's administration has also taken a few emergency steps. Primary schools in several cities have been closed for a week, with parents advised to make their children wear masks.
