Intense cold wave conditions and dense fog continue to disrupt normal life across several northern states, with the India Meteorological Department (IMD) issuing a red alert for Uttar Pradesh amid persistent foggy conditions.
 
The national capital remained in the grip of a cold wave, with the sun largely obscured by clouds and pollutants lingering in the atmosphere, leading to reduced visibility. At least 129 flights were cancelled at Delhi airport on Saturday due to dense fog, reported PTI.
 
The IMD has issued fresh alerts for cold wave conditions, dense fog and snowfall across multiple regions, warning of further temperature fluctuations in the coming days.
