Geneva - An 82-year-old woman was found dead in a Swiss stream on Sunday, police said, as heavy rain and landslides halted train and road traffic near the capital Bern.

Police said that the woman died in Thoerishaus, a village south-west of Bern as parts of the country were hit by a deluge.

In the nearby town of Koeniz, 200 firefighters worked throughout the night to deal with flooded streams and landslides, evacuating several homes.

Landslides blocked the railway between Bern and the western city of Fribourg and between Montreux and Zweisimmen, while flooding cut the line between the capital and the town of Thun, Swiss Federal Railways said.

Flooding also forced the closure of several roads in the region, national road company Viasuisse said.

Bern and Fribourg were hit by heavy rain that began on Saturday and continued non-stop until midnight. - Sapa-AFP
