In the New York times article, Frenzy of Rape in Congo Reveals U.N Weakness, The journalist describes how rape and piliging have been a huge problem in the Congo for a while now, and the U.N hasn't been effective in stopping the rebel militias. The Congo is being called the U.N's biggest failure. In one instance 150 people were killed within ear-shot of a U.N base.

NPR wrote an article describing the problems that arose when the Rawanda soldiers crossed into the COngo to pursue the rebels, but were targeting civilians as well. Rawanda seems to be causeing a lot of problems for the Congo, and the the Congo seems to be a playground for outlaws.
These articles share a common theme about the disappointment over the U.N's poor effort.
