Cholera riots in Haiti spreads

Protests against United Nations peacekeepers and Haitian authorities have spread to the country's capital.



Police have fired teargas as gangs of youths blocked roads in Port au Prince by setting up burning barricades.



UN and non-governmental organisation vehicles were also pelted with rocks.



The disturbances follow days of rioting in northern Haiti over suspicions that UN soldiers introduced a cholera epidemic that has killed more than 1,100 people.



Meanwhile, health experts in the United States say the infection could stay in Haiti for years to come.
