**The widow of former Rwandan President Juvenal Habyarimana, whose assassination triggered the Rwandan genocide, has been arrested in France.**Agathe Habyarimana is accused by the current Rwandan government of helping to plan the 1994 genocide, and has long been sought by prosecutors there.
Mrs Habyarimana, who has been living in France for several years, denies the accusations.
More than 800,000 Tutsis and moderate Hutus died in the massacres of 1994.
French officials said Mrs Habyarimana was detained in the Paris region by police executing a Rwandan-issued international arrest warrant.
Her arrest follows a visit to Rwanda last week by French President Nicolas Sarkozy, when he admitted that France - and the wider international community - had make “mistakes” over the genocide.
President Habyarimana died in April 1994 when his jet was hit by a missile as it descended towards the Rwanda capital Kigali.
Hardline ethnic Hutu supporters of the president then launched the apparently pre-planned massacres.
