The bus crashed at about one a.m. on a slippery road, and crashed into a bank of snow on the side of the road.

Norwegian media say that most passengers suffered only minor injuries, with three passengers hospitalized, and one of them may have had their leg broken.
Marina Avidana, a Russian woman living in Stockholm, said on Facebook that several Rigans had been on the bus.
"Rescuers pulled me out via the windshield. A guy from Riga broke the glass, it wasn't that easy! The crash happened six km away from the border between Sweden and Norway.. I made friends with the driver who was resting and with several guys from Riga," she wrote.
Local police told Rus.lsm.lv that they've yet to determine what were the nationalities of the people on the bus. "But I know that the bus was from Germany and its driver was from the Czech Republic," a representative of the police told Rus.lsm.lv.
The Foreign Ministry has yet to learn whether Latvian nationals were on the bus and whether they've been injured, but it plans to obtain said information as soon as possible, the ministry said.
