Foreign mercenaries in Iraq

So it seems that the side that is bringing African mercenaries is the US and not Qadhdhafi:  "Already, the Ugandan government says there are more than 10,000 men and women from this poverty-stricken East African nation working as private security guards in Iraq. Hired out to multibillion-dollar companies for hundreds of dollars a month, they risk their lives seeking fortunes protecting US Army bases, airports, and oil firms." (thanks Therese)
