Seven dead in Siberian mine accident
On Friday a group of around seven people went down illegally to look for tungsten ore in the disused mine despite warnings that it wasn't safe.
When they encountered a build-up of gas, one escaped and brought around a dozen locals to help. Down the mine, the newcomers were also affected by gas. Only some ten of them managed to return.
Rescuers from neighbouring regions are working alongside a local team to find the missing men.
