Tension is mounting in Haiti as UN forces and local police try to quash the gang violence which has left at least 50 people dead over recent weeks. Armed groups loyal to former president Jean Bertrand Aristide are locked in combat with ex soldiers who helped topple the previous leader. The attacks come on top of storms and floods in September which left more than 3,000 people dead. South Africa has rounded on Haiti's interim leader - Gerard Latortue - dismissing accusations it is allowing Aristide to coordinate a violent uprising from his exile there. Meanwhile, nearly 100 Chinese riot police have arrived in Haiti under UN control - the first Chinese troops to be deployed to the Western Hemisphere. China does not have diplomatic relations with Haiti, which recognizes the self-governing island of Taiwan. **PHOTO CAPTION*** British soldiers patrol the center of Basra, southern Iraq, Tuesday, Oct 19, 2004.
