More than a thousand people in Sweden had to be rescued after they became trapped in their vehicles for nearly 24 hours following heavy snowfall.
Rescue teams and the military worked overnight to evacuate stranded people on the E22 main road between the towns of Horby and Kristianstad in the Nordic nation's far south on Wednesday night.
Ploughs had failed to remove the snow drifts that had caused gridlock on the motorways.
Many cars were abandoned as the evacuation continued, while others were able to turn around as rescue workers cut holes in the metal barriers separating southbound and northbound lanes, news agency TT reported, citing rescue services.
