Massive explosion in abandoned South African gold mine kills 31 suspected illegal miners, authorities say

At least 31 people died in a gas explosion in a disused mine shaft in South Africa in May.
Most of the bodies remain trapped underground due to dangerously high methane gas levels.
The incident likely involved illegal miners from Lesotho working in the abandoned mine.
Illegal mining is common in South Africa's disused gold mines, where fatal accidents frequently occur.
The Harmony Gold-owned mine closed in the 1990s but remains flooded with methane gas.
