New Delhi:
A dense "freak" fog has covered Delhi's Indira Gandhi International Airport this morning. Both runways were shut down, as visibility was described as nil. The situation has began to improve now.
40 flights have been delayed so far, and this could affect flight schedule for some part of the day.
A passenger on an early morning Indigo flight to Kolkata said they had boarded as scheduled and had now been sitting in the plane for the past one and a half hours. "We cannot see anything outside the window... every few minutes a further delay is being announced", he said.
The sudden foggy morning came after about two weeks of clear skies in the capital. Sunday was clear and pleasant with the maximum temperature at 22 degrees Celsius, three degrees above the season's average.
The weatherman said moisture in the air which did not come down as rain, had caused the fog.
