AU-PRINCE, Haiti, Feb. 26, SPA-- One Brazilian peacekeeper was wounded Saturday and the charred body of a man burned alive with a tire around his neck lay in the deserted street of a slum where shots rang out and people peered fearfully from barred windows. It was the second day of violence in Bel Air, where at least two civilians were shot and killed Friday, allegedly by Haitian police, and the U.N. mission reported two Brazilian troopers were shot by snipers. Bel Air is a warren of alleyways lined with tin-roofed homes on a hillside behind the National Palace where Haitian police have been struggling for months to regain control from armed militants loyal to ousted President Jean-Bertrand Aristide. Brazilian troops in armored cars with mounted submachine guns moved into Bel Air early Saturday and came under fire, said Cmdr. Carlos Chagas Braga, a spokesman for the 7,400-member U.N. peacekeeping mission led by Brazil. A bullet from a high-velocity weapon ricocheted off one vehicle, sending fragments into a soldier's face and shoulder, said Chaga. He said two other Brazilian peacekeepers were shot in the arm in two similar attacks Friday. «These injuries were minor,» Chaga said. At least nine peacekeepers have been wounded since the mission began in June. He said in both instances U.N. troops did not return fire because of a policy of «shoot only when you can see your target.»
