South Africans Burn U.S. Flag To Protest Obama REUTERS: America's star spangled banner up in flames ahead of U.S. President Barack's Obama's official state visit to South Africa scheduled to begin Friday. Mostly from the NObama movement, demonstrators in Pretoria said the visiting leader comes up short when compared to their ailing national hero Nelson Mandela. Among complaints -- Obama's policy of targeting militants in other countries often via drone attacks ... The U.S. president's Africa trip is part of efforts to rectify what some consider neglect on African partnerships from the United States' first black leader. Obama may also meet with Mandela, who is in critical condition in hospital over a recurrent lung condition. Further demonstrations are also expected in Johannesburg and Cape Town.
