Illegal mining continues to be widespread in South Africa, where miners enter abandoned shafts to search for remaining deposits.

An estimated 4,000 illegal gold miners are hiding underground in South Africa after the government cut off food and water in an effort to "smoke them out" and arrest them. The miners have been in a mineshaft in Stilfontein, in the North West province, for about a month.

Officials are hoping the strategy will force the workers out of the mineshaft and to the surface, where they will be arrested.
