While some of the deaths were due to exposure, at least six people were killed in road accidents caused by dense fog, the report said. All schools and colleges in Uttar Pradesh's capital, Lucknow, have been closed until January 5 because of the cold. The fog disrupted air and rail traffic across northern India. At least 15 flights leaving from New Delhi airport were cancelled and 100 trains were running behind schedule, state-run Doordarshan television reported.
