Visibility on both the runways was below 50 metres - a minimum of 125 metres is required for flights to take off.
Fog started engulfing the airport last night and was too dense by this morning.
There was thick fog in south Delhi as well and on the toll road connecting the Capital to Noida. Visibility was almost zero in stretches on the Outer Ring Road.
A shallow cover of fog has hung over Delhi for the past few mornings, but it cleared up as the day progressed.
