Flights diverted, trains delayed: New Delhi sinks in dense fog as India shivers from cold

Several flights have been diverted and almost three dozen trains are running behind schedule as a thick blanket of fog covered New Delhi amid an unusually severe winter season in India.
Photos and videos shared on social media Monday morning show the Indian capital and its suburbs fully consumed by impenetrable fog.
The latest weather surprise comes just a day after temperatures in New Delhi plummeted to 2.5 Celsius (36.5 Fahrenheit), forcing the Indian Meteorological Department (IMD) to issue a “red warning”. The air quality in the national capital remains in the “severe” category since Sunday.
