Driving in New Delhi is known to be dangerous. Now try with the fog the Indian capital woke up to for the New Year, thought to be the thickest seen this season.
"There is so much fog that drivers cannot even see the road," said Sudhir, a local resident who said he had to switch on all of the lights on his car to see and be seen.
The extremely poor visibility caused hundreds of flights to be suspended at the city's Indira Gandhi International Airport on Monday (Jan. 1), leaving passengers stranded, and locals waiting for hours for their loved ones to arrive.
Dozens of trains were also cancelled, with passengers left in the cold at New Delhi's railway station as temperatures dropped to 8 degrees Celsius.
New Delhi is one of the world's most polluted cities, according to World Health Organisation data.
India's weather service expects the fog to stick around for another three days. Tourists in the area may be about to bring home some unusual holiday pictures.
