Storm blows away tents at Swiss gymnastics festival

A powerful freak storm has blown away tents at a gymnastics festival in Switzerland.

Winds of 80mph hit the Swiss Federal Gymnastics Festival in Biel on Thursday.

Other parts of the country have also been hit by heavy rain and hailstones the size of golf balls!

Geneva Airport has been flooded and several people have been injured by the freak weather.

Weather experts say it's been caused by a mix of snow melting suddenly in the Alps and a return to cooler conditions.
