A thick layer of fog engulfed Punjab as the minimum temperature in Ludhiana is likely to remain at 2 degree Celsius for December 25 and 26.
Minimalistic visibility due to dense fog created problem for the people travelling to work.
In order to provide some relief, tea 'langar' was set up by volunteers in Amritsar.
Locals in Ludhiana claimed that this kind of weather used to be 15 years back.
