A mine collapse in South Africa has left nine miners dead, the BBC reports. The miners were trapped underground after a shaft fell. Since the incident on Monday at Impala Platinum, all bodies of the deceased have been found. The mining company released a statement about the tragedy. “We have set aside Friday as a day of mourning across our operations,” it read.  “Our thoughts are with the families and friends of our employees at this time,” David Brown, the head of Impala Platinum, said. South Africa has some of the deepest mines in the world, and accidents are not uncommon, reports the BBC. Sixty people were killed at a mine fire last month.
