A mine collapse 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 follows a similar event in January that also left over 200 dead in an area already facing a humanitarian crisis and ongoing conflict. FRANCE 24's Emmet Livingstone has more from Kinshasa about a strategic mine, which produces 15% of the world's tantalum.
