DAKAR, Senegal (AP) — A landslide that collapsed several tunnels at a major coltan mine in eastern Congo is reported to have left at least 200 people dead in the rebel-controlled site. Rebels and government spokespeople traded accusations of responsibility and disputed the death toll, however analysts say that the collapses are the deadliest in years. 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.
