The U.N. human rights commissioner said that Burundi has agreed to set up a tribunal to try people suspected of genocide and war crimes during the central African nation's 12-year civil war.

Louise Arbour said the government will not give amnesty for war crimes, genocide, crimes against humanity and other serious violations.

"We now have an important consensus (with the government) on the fact," she said at the end of her five-day visit to Burundi, which is still reeling from the war that killed more than 250,000 people.

There was no immediate timetable for setting up the tribunal.

Burundi has long been riven by tension between the majority Hutus and minority Tutsis, who have dominated the government, economy and military since independence from Belgium in 1962.

Hutu-Tutsi animosities have brought bloodshed elsewhere in the region — including the 1994 slaughter of a half-million Tutsis and moderate Hutus by militant Hutus in neighboring Rwanda.

President Pierre Nkurunziza was elected in 2005 as part of a Hutu-dominated government to replace a power-sharing administration that oversaw the postwar transition. The civil war killed more than 250,000 people.

Nkurunziza's administration has been wracked by accusations of corruption and abuse.
