At least 78 people have died after authorities imposed a blockade on an illegal gold mine here, part of a monthslong standoff between prospectors and a government determined to force them to surface—often by cutting off their food and water.

South African rescuers have so far pulled 78 bodies and rescued 166 people from the Stilfontein gold mine over three days of operations, police spokesperson Athlenda Mathe told reporters at the scene on Wednesday.
