New Delhi, Jan 13: Delhiites on Saturday woke up to a moderately foggy morning with maximum temperature at 23 degrees and minimum temperature at 7 degrees. Due to the decreased visibility and operational reasons, a total of 41 trains were delayed, four rescheduled and 13 cancelled.

The fog cover also hit the flight operations at the Indira Gandhi International Airport (IGIA) on Saturday.

Meanwhile in Chennai, 12 arriving flights were diverted and nearly 30 departing flights delayed in view of smoke due to burning of old articles on Bhogi festival.

Between 4 AM to 8 AM, both the incoming and the outgoing air traffic suffered. The services were expected to resume after 9 AM.

As many as 18 arriving flights were diverted to Bengaluru and Hyderabad airports. They flew in from various destinations such as Kuwait, Sharjah and Delhi.

No flights took off during this period, resulting in delays and scores of passengers waiting at the airport.

Bhogi, celebrated ahead of the Tamil harvest festival Pongal tomorrow, involves burning of old articles in a symbolic gesture of bidding adieu to the old and welcoming the new.

Meanwhile, motorists plied their vehicles with their headlights on following the smoke cover which descended on the city and its neighbourhoods.
