CBS News reports on the Congo civil war. The first part of the investigation finds that the efforts to stop the war have failed, "in part because Western companies are helping pay for it." Coltan, a mineral essential for the production of computer chips and high-tech devices, has kept the war going because African governments, middlemen and rebels have become "interested in loot as much as politics." The second segment reports on a land dispute in Zimbabwe, which has caused racial conflicts. The threats to white farmers and business-owners have forced some of them to try to escape to South Africa.
