South African authorities blockade mine with 4,000 people inside

South African authorities are involved in an operation to close an illegal gold mine in Stilfontein, with reports suggesting that between 1,000 and 4,000 miners may be trapped underground. The miners are believed to be suffering from a lack of food, water, and other basic necessities, with some reports estimating that they may have been underground for several weeks. In an effort to force the miners to return to the surface, the authorities have cut off their supplies.
