A heavy blanket of fog enveloped the national capital on Thursday morning, hitting air, rail and road services badly.
According to the MeT department, the general visibility at the Indira Gandhi International Airport dropped to below 50 metre and because of poor visibility operations of more than dozen of flights were affected.
Train services were also affected due to fog.
Road traffic was equally chaotic as the motorists tried to navigate through the dense fog.
North India usually witnesses early morning fog every winter when night temperatures often dip below five degrees Celsius.
