Officials monitor expanding Russian sinkhole
A crater in Russia, which emerged 10 months ago has tripled in size to become a 120m-wide sinkhole.
The sinkhole, near the town of Solikamsk, is believed to have been caused by flood erosion in an underground mine.
The collapsing soil has already claimed a number of holiday homes, but officials say local people are not in danger.
