GOMA, Congo (AP) — A mine collapse on Tuesday at a major coltan mining site in eastern Congo left at least 200 dead, according to Congolese authorities, a number disputed by the rebel group that controls the mine.

The collapse took place Tuesday at the Rubaya mines, which are controlled by the M23 rebels, Congo’s Ministry of Mines said in a statement on Wednesday, the latest such accident in the country’s mineral-rich and rebel-controlled territories.

Fanny Kaj, a senior official in the M23 rebel group, which controls the mines, disputed the figure and said that the collapse was caused by “bombings” and only five people had been killed....

Rubaya lies in the heart of eastern Congo, a mineral-rich part of the Central African nation which for decades has been ripped apart by violence from government forces and different armed groups, including the Rwanda-backed M23, whose recent resurgence has escalated the conflict, worsening an already acute humanitarian crisis.

Congo is a major supplier of coltan, a black metallic ore that contains the rare metal tantalum, a key component in the production of smartphones, computers and aircraft engines.

The country produced about 40% of the world’s coltan in 2023, according to the U.S. Geological Survey, with Australia, Canada and Brazil being other big suppliers. Over 15% of the world’s supply of tantalum comes from Rubaya’s mines.
