Intense cold wave coupled with dense fog led to the death of 12 persons -- nine in Uttar Pradesh and three in Punjab.
Hilly regions of Jammu and Kashmir and Himachal Pradesh reeled under temperatures below the freezing point, while dense fog in the plains caused low visibility affecting flight operations and delaying around 100 trains on Thursday.
Delhiites on Friday woke up to another chilly morning with moderate to dense fog engulfing the city which continued to disrupt rail traffic with 8 trains cancelled and 79 delayed.
