South Africa has the fourth largest security contingent in Iraq. Many security workers are members of the old South African Defence Force and earn up to $30,000 per month. "We are here to protect ourselves and the people we work with from elements that want to kill us," states Marius van der Riet. But there's growing concern about the actions of these foreign mercenaries who are accountable to no-one and subject to no international laws. And the quest for big contracts and loads of money could bring another kind of danger. "Their participation in theatres of war is in conflict with the Foreign Military Assistance Act," states South Africa's Defence Minister Mosuia Lekota. "If we are able to identify them, they will be arrested."
