Abandoned South African gold mine claims 31 lives in explosion.
At least 31 people, believed to be illegal miners from Lesotho, are suspected to have died in an abandoned South African gold mine in mid-May. The cause of death is unknown, and 28 bodies are still believed to be underground due to high levels of methane. The mine was previously owned by Harmony Gold Mining Company and stopped operations in the 1990s. Thousands of unregistered miners, known as "zama zamas," operate in South Africa, scavenging obsolete mines for gold.
