A quick update of the sexual violence statistics. Here are the most recent stats from UNFPA for this year, across the whole Congo. Most of the sexual violence is in North and South Kivu, most of it affects girls between 10-17 and - surprisingly - only 1/3 of the perpetrators are reported to be soldiers (although for North Kivu the figure is 52% and for South Kivu 86%).
7,685 cases reported in total for the first 6 months of 2010, including 2,275 for South Kivu and 2,245 for North Kivu.
Bear in mind that there is a large amount of under-reporting, and what qualifies as "sexual violence" may vary significantly.
