A Rwandan official has called for legal action against France over its alleged role in the 1994 genocide in Rwanda.
Some 800,000 people were killed in the 1994 genocide
Aloys Mutabingwa, a representative at the International Criminal Tribunal for Rwanda, said the court had heard enough evidence of France's involvement.
He said some 100 Rwandans wanted by the court or by Rwandan prosecutors were "comfortably living in France".
At least 800,000 people, mostly minority Tutsis, died in the massacres between April and July 2004.
French were individually and collectively responsible for allowing the massacre to unfold, he said.
"I would like to seize this opportunity to urge the United Nations and the French government to make sure these people are put under investigation and prosecuted," he said at a press conference in Tanzania.
"The testimonies heard by this tribunal during the last 10 years are probably sufficient to indicate that there is some damning evidence" of French responsibilities, AFP news agency reported him as saying.
Some witnesses have claimed that French troops were involved in the training of Interahamwe militias, which carried out most of the killings.
He added it was only in order to avoid "a diplomatic incident" that the tribunal's prosecutor had not yet named France as one of the countries which refuse to co-operate with the inquiry.
France has always denied any direct involvement in the massacres.
