The roof of a sports centre used for ice skating events at the 1984 Winter Olympics in Bosnia collapsed Sunday under the weight of heavy snow, police said. No injuries or fatalities were reported.

The Skenderija sports centre in downtown Sarajevo was closed and nobody was inside when the roof collapsed just after 3 p.m. (1400 GMT; 9 a.m. EST), police spokesman Irfan Nefic said.

A policeman guarding the site said it sounded like an explosion. He spoke on condition of anonymity because he wasn't authorized to speak to the media. Surrounding shop windows were broken.

The Skenderija centre, made up of three different complexes, was built in 1969 and used during the Olympics for both figure skating and ice hockey. Only the ice skating complex was affected.

For more than a week, Bosnia has been paralyzed with record snowfall. There was up to 90 centimetres (around three feet) of snow on the ground in Sarajevo on Sunday.

Temperatures as low as -22 C (-8 F) throughout the week have made it difficult to clear the snow. Authorities have closed schools and universities and traffic is possible only down main streets and those that lead to hospitals. They also urged people to shovel in front of their buildings and try to clear their roofs. Snow is being loaded on trucks and dumped into a river, but more snowfall overnight again covered the cleared streets
