According to the Met Office, the thick blanket of smog once again descended over Lahore that forced the citizens to take precautionary measures as the Air Quality Index (AQI) hit 408 on Tuesday morning.

With no sign of its reduction at least in the next few hours, Lahore's AQI witnessed a sudden spike of 177 points within 24 hours. The weather experts said that the sudden rise in smog stemmed from the smoke and other pollutants from Indian Punjab's burning crops.
