Rebel authorities in eastern Congo say at least 200 people were killed in a landslide at coltan mines. The collapse happened Wednesday due to heavy rains at the Rubaya mines, controlled by M23 rebels. Many victims remain buried in the mud. Several others were injured and taken to health facilities in Rubaya. The rebel-appointed governor has halted mining and ordered relocations near the site. 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. Rubaya alone provides more than 15% of the world's supply of the metal. Conflict in eastern Congo has created one of the world’s largest humanitarian crises with more than 7 million people displaced.
