Oslo: Norwegian rescuers deployed drones and dogs to negotiate unstable clay soil in a search for 10 people still missing after a landslide in southern Norway swept away more than a dozen buildings the previous day.
Another 10 people were injured, one critically, after the landslide in the residential area in the Gjerdrum municipality, about 30 kilometres north of the capital, Oslo.
Conditions remained challenging, with the clay ground still too unstable for emergency workers to walk on and temperatures registering minus 1 degree Celsius at 0600 GMT.
The edges of the crater continued to break away, authorities said, asking people not to approach the area. Some 1000 people have so far been evacuated.
