Falling trees have killed at least three people as hurricane-strength winds whipped across southwestern Sweden, leaving more than 260,000 households without power.
Winds of up to 137 kph also caused major disruptions in train and boat traffic across Scandinavia on Sunday, and police in Norway and Sweden urged people to stay indoors to avoid what was described as the biggest storm in two years.
Police said a 9-year-old boy was killed by a falling tree in Motala, about 250 kilometres southwest of Stockholm. A 60-year-old man in the city of Jonkoping and a 25-year-old man in Ullared, near the southwestern coast, also died when their vehicles were struck by trees.
The bridge connecting Sweden and Denmark was temporarily shut to all traffic, while nearly all train departures in southern Sweden and parts of Norway were cancelled, as the strong winds felled trees across the tracks in several places.
The central train station in Sweden's second-largest city, Goteborg, was left without power, and several ferry lines between Denmark, Norway and Sweden cancelled sailings, officials said.
