Heavy snowfalls brought chaos to parts of Germany and Sweden on Friday, leaving roads blocked, trains halted and schools shut.

The Red Cross helped drivers stuck on a motorway in the southern German state of Bavaria as schools and rail services were also hit. A nine-year-old boy was killed by a falling tree on Thursday.

A boy of nine was killed near Munich when a tree collapsed under the weight of snow. It was 40 minutes before he was found and emergency services were unable to revive him.

There was some respite in Austria on Friday, after three metres of snow fell in some parts in previous days. Seven people have died in the past week and two hikers have been missing since Saturday.

"Such quantities of snow above 800m altitude only happen once every 30 to 100 years," said Alexander Radlherr from Austria's Central Institution for Meteorology and Geodynamics.

Swedish reports spoke of hurricane force winds in parts of the north. One area recorded winds of 49.7m per second (111mph) as Storm Jan ravaged Stekenjokk near the Norwegian border.

Conditions on Friday were particularly treacherous in Bavaria, where the local broadcaster said snowfalls were paralyzing public life.

Roads in the Berchtesgaden area close to the Austrian border were blocked and the army sent up to 200 soldiers to help hundreds of people caught up in the snow.

In Switzerland, an avalanche hit a hotel restaurant, injuring three Folk.
