One person missing and Blatten devastated after huge cloud of ice and rubble inundates evacuated town

A huge section of a glacier in the Swiss Alps has broken off, causing a deluge of ice, mud and rock to bury most of a village evacuated earlier this month due to the risk of a rockslide.

Drone footage broadcast by Swiss national broadcaster SRF showed a vast plain of mud and soil completely covering part of the village of Blatten, the river running through it and the wooded sides of the surrounding valley.
