A huge mass of rock and ice from a glacier thundered down a Swiss Alpine mountainside, sending plumes of dust skyward and covering with mud a village in the valley below that authorities had evacuated

Videos on social media and Swiss TV showed the mudslide near Blatten, in the southern Ltschental valley. Houses and buildings were partially submerged under the brownish mud mass. Local police said a 64-year-old man was reported missing. Search and rescue operations involving drones with thermal cameras were ongoing.
