A French court has rejected a Rwandan bid to extradite the widow of ex-President Juvenal Habyarimana, whose killing sparked the 1994 genocide.
Agathe Habyarimana, 69, is accused by the Rwandan authorities of helping to plan the genocide. She denies the accusations.
French forces flew her out of Rwanda shortly after the violence began and she has lived in France for years.
More than 800,000 Tutsis and moderate Hutus died in the massacres.
Juvenal Habyarimana, a Hutu, was killed when his plane was shot down above Kigali airport on 6 April 1994.
Within hours a campaign of violence, carried out mostly by Hutus against Tutsis, spread from the capital throughout the country.
The Hutu militias blamed the Tutsis for shooting down the president's plane, although it was unclear who shot the plane down.
After the Paris court gave its judgement, Mrs Habyarimana told journalists: "I'm relieved, I've always had faith in the French justice system."
Mrs Habyarimana also faces a case in France's civil courts brought by rights activists.
But her lawyer, Philippe Meilhac, said the extradition ruling would cause problems for the civil case.
"We can't stay like this for ever. The very serious accusations against Mrs Habyarimana are old and completely denied by Mrs Habyarimana," he said.
