Sweden's main airport, Arlanda, was paralysed on Wednesday due to a snowstorm in the country's capital, just as winners of this year's Nobel prizes were due to arrive to receive their awards.
Around 30 cm of snow fell overnight in the Stockholm area between Tuesday and Wednesday and the weather office warned another 20 cm was on the way.
"There are a limited number of flights out of Arlanda (the main airport) but no arrivals. There are no departures or arrivals from Bromma (a smaller airport closer to the city centre)," said a spokeswoman for airport operator Swedavia.
Arlanda airport's website itself was so busy due to worried travellers trying to check the traffic situation that people were put in a queue to view it.
The foundation which oversees the SEK8 million kronor (USD$1.21 million) Nobel prizes said several laureates were due to arrive in Stockholm on Wednesday. This week sees a series of news conferences and lectures, in the run up to the formal handing over of the prizes and a gala banquet on Monday.
