Paris: French prosecutors have requested the dismissal of a probe into the deadly 1994 attack on former Rwandan president Juvenal Habyarimana, which sparked the country's genocide, according to legal papers seen by AFP on Saturday.

In their final statement dated October 10, prosecutors demanded that the charges be dropped against seven suspects because investigators had not been able to gather "sufficient evidence".

Rwanda's genocide has caused two decades of tension between Paris and Kigali, which accuses France of complicity in the killings through its support and military training for Habyarimana's Hutu forces who carried out most of the slaughter.
