AIR correspondent reports that people preferred to stay indoors as this was one of the coldest day of the season so far.”People in Delhi preferred to remain within the warm environs of their homes for most part of the day to protect themselves from the biting cold. With mercury falling as low as ten degrees below normal, the capital is shivering in this chilling winter.And fog has only worsenned the situation by disrupting road, rail and air traffic.
