The schedule of several flights and trains was disrupted Friday morning as a dense fog covered Delhi. The city traffic police had to issue an advisory to commuters to drive with caution. According to officials, at least a dozen flights were put on hold at the Delhi airport in the morning for nearly three hours because of low visibility conditions. The schedule at the IGI Airport at Delhi was affected from 5:30am to 7am and at least five flights, including one from Singapore, were diverted to other airports.
