A interesting little PDF file put out by the UN in 2004.

Summarizing “Many of the 72 allegations originally reported to MONUC could
not be substantiated or even fully investigated because of their non-specific nature.
Nevertheless, OIOS was able to compile 20 case reports.

One case that was substantiated involved an international civilian post.
The remaining 19 cases involved peacekeepers from 3 contingents.
Of those, six cases were fully substantiated, and under-age girls were involved in all of them.

The final recommendation of this report included “the public naming and shaming of those found to have engaged in sexual exploitation and abuse; and the permanent exclusion from peacekeeping missions of those troops who engage in sexual exploitation and abuse
and of their contingents’ commanders (ID Rec. No. IV04/141/08).

We are endeavoring to help them with that recommendation
