Who was involved in the conflict of blood diamonds?

Many terrorist organizations and some governments are involved in the trade of blood diamonds. Because this criminal activity happens out of the public eye, it is difficult to name the 'who' that are involved.

However, Wikipedia documents these geographies, with some reservations:

• Angola
• Liberia and Sierra Leone

• Côte d'Ivoire

• The Democratic Republic of the Congo
• The Republic of Congo
• Zimbabwe
