Rwandan-born Isaak Kamali, a naturalised French citizen who has been on France's judicial radar since 2009, was charged with "genocide" and "crimes against humanity".
Kamali was condemned to death, in absentia, by a court in Rwanda in 2003, but this sentenced was later "annulled" due to changes in Rwandan law, according to a French-based victims' association, the Collective of Civil Plaintiffs for Rwanda (CPCR).
