Three missing in Swiss floods as Alpine resort Zermatt cut off

Three people are missing after floodwaters swept through the south-eastern Swiss town of Misox in the alpine valley of Graubünden.

A massive thunderstorm on Friday night caused rivers to break their banks, flooding streets and causing several dozen residents to be evacuated from their homes, local authorities said.

Further west, the alpine resort of Zermatt has been isolated by floodwaters.
