United Nations ? The United Nations will ask France to take legal action against a former U.N. employee accused in the killings of 33 Rwandans in the 1994 genocide, after an internal review found the world body bungled his case and failed to protect its Rwandan staff.

Callixte Mbarushimana, who has lived under refugee protection in Paris since 2003, vehemently denies the charges and says he would welcome his day in court. Rwanda has a warrant for his arrest on charges of genocide and crimes against humanity.

For the last year, U.N. officials have quietly pressed Rwandan authorities and the U.N. war crimes tribunal for Rwanda to seek his extradition, without success, and are turning to France.

“We’ve exhausted the possibilities,” Mark Malloch Brown, chief of staff to Secretary-General Kofi Annan, told The Associated Press. “We are going to ask the French authorities where he’s resident to pursue a case against him.”

French justice officials refused to comment until they get the request from the U.N. Development Program. U.N. officials, who agreed to discuss the request only on condition of anonymity because the note had not yet been delivered, said the note would not specify whether France should prosecute Mbarushimana or extradite him to Rwanda.

Mbarushimana, who now refurbishes computers in Paris, denies the accusations.

“I’m innocent of everything they accuse me,” Mbarushimana told AP. “What happened in Rwanda is horrific. I do not really find any words to qualify that. It was horrendous. And I don’t see anything which could justify such acts of barbarism.”
