Police in Uganda arrested one of the four most-wanted suspects from Rwanda's 1994 genocide, Idelphonse Nizeyimana, after he entered the country by bus last week from neighboring Democratic Republic of Congo.
A former Rwandan army captain and senior intelligence officer, Nizeyimana is accused of organizing the slaughter of Tutsi civilians and ordering the slaying of a former queen of Rwanda.
He was caught in a suburb of the Ugandan capital, Kampala, then extradited to Arusha in northern Tanzania to face trial at the International Criminal Tribunal for Rwanda.
The United States had offered a $5-million reward for his capture. The U.N. court says Nizeyimana and others prepared lists of Tutsi intellectuals and those in authority in Rwanda before handing the lists to troops and militia fighters who killed them.
He is accused of setting up roadblocks where Tutsi civilians were slaughtered, and of providing weapons and transportation to militia fighters in the knowledge they were being used for such attacks.
The tribunal says Nizeyimana also sent soldiers to the home of the former queen of Rwanda, Rosalie Gicanda -- a symbolic figure for all Tutsis -- who then executed her on his orders.
More than 800,000 ethnic Tutsis and politically moderate Hutus were killed in 100 days of bloodshed in 1994. Nizeyimana is charged by the U.N. tribunal with genocide, complicity in genocide, and direct and public incitement to commit genocide.
