One of the nine most-wanted fugitives in the 1994 Rwandan genocide, Ladislas Ntaganzwa, the former mayor of Nyakizu, was arrested by Interpol agents in Goma, Congo, this week, the Associated Press reports.

More than 800,000 ethnic Tutsis and moderate Hutus died in that genocide, John Bosco Siboyintore, head of the genocide tracking unit at Rwanda’s Public Prosecution Authority, said. The United Nation’s international criminal tribunal closed its proceedings last week after nearly 20 years, transferring Ntaganzwa’s case to Rwanda.

The United States had offered a $5 million reward for information leading to Ntaganzwa’s capture, the New York Times reports. Accused of helping to organize the massacre of more than 20,000 Tutsis, he faces charges related to participation in genocide and incitement to commit genocide:

Nearly 22 years ago, Mr. Ntaganzwa was in his early 30s and a mayor, exercising “absolute authority, control and effective control over his subordinates” during the Hutu government’s genocide against the minority Tutsis, according to his 1996 indictment.

From his position, Mr. Ntaganzwa oversaw the murder of thousands of his countrymen in the area he administered, as well as the rape and sexual violence committed against women, the United Nations said in its statement. On April 14-15, 1994, his indictment said, Mr. Ntaganzwa distributed weapons to civilians surrounding a parish where thousands of Tutsis had taken shelter, then used a megaphone to order them to shoot into the crowd. Several days later, it said, he helped organize another massacre on a nearby hill.

“He personally participated in these crimes,” his indictment says.

Ntaganzwa had been a fugitive for 21 years, the AP reports.
