I have been following the news coming out of the Congo for some time but just came across this Economist article which provides a good overview of the situation. From the article:
Another humanitarian disaster is unfolding in eastern Congo
THE war that raged in the Democratic Republic of Congo, mostly in the east of the country, between 1998 and 2003, claimed millions of lives and sucked in plundering armies from Rwanda, Uganda, Zimbabwe, Angola and Namibia. The scale of the misery caused by that conflict—and the importance of Congo’s massive mineral wealth—explains the anxiety among ordinary Congolese, diplomats, aid workers and others, following the advance this week of a Tutsi rebel army towards the town of Goma in eastern Congo. If Congo falls apart again, the humanitarian cost would be enormous.
