UN peace-keepers accused of child abuse

The world has come to depend on peace-keepers (deputed by the United Nations) to step in where individual countries and their forces cannot step in. Over the past few decades, the peace-keepers have gone to so many countries (especially in Africa) where they have come to represent the commitment of the international community to help out the citizens of countries that are having leadership or governance problems and need help. So it is all the more shocking that these same peacekeepers have been pointed out in a report as being responsible for many crimes such as the exploitation of young children, pornography, and trafficking of children:

Humanitarian aid workers and United Nation peacekeepers are sexually abusing small children in several war-ravaged and food-poor countries, a leading European charity has said. After interviewing hundreds of children, the charity said it found instances of rape, child prostitution, pornography, indecent sexual assault and trafficking of children for sex.
Save the Children says that almost as shocking as the abuse itself is the "chronic under-reporting" of the abuses. It believes that thousands more children around the world could be suffering in silence. In 2003, U.N. Nepalese troops were accused of sexual abuse while serving in the Democratic Republic of Congo. Six soldiers were jailed. A year later, two U.N. peacekeepers were repatriated after being accused of abuse in Burundi, and U.N. troops were accused of rape and sexual abuse in Sudan.

Such incidents are very shocking, and need a detailed investigation. The peace-keepers operate in regions where there is very little authority, and where people are even otherwise subject to all sorts of conditions; and if there are fears that they will start behaving in such a manner, trust will be lost.
