A United Nations soldier in Haiti was killed as U.N. forces retook control of a local police station seized by former Haitian forces.
Officials say two other U.N. troops were wounded in the gunbattle, which took place in Petit-Goave, west of Port-au-Prince.
The Associated Press reports U.N. troops detained 20 people after the clash.
The former troops have demanded that the government restore the army, which former president Jean Bertrand Aristide disbanded in 1994.
U.N. peacekeepers and the interim government have been struggling to contain violence since Mr. Aristide was removed from power in February 2004. Elections are scheduled for November.
