A senior aide to Rwandan President Paul Kagame is to be transferred from detention in Germany to French custody next week, officials say, BBC reported.
Rose Kabuye was arrested in Germany on Sunday accused of involvement in the destruction of a plane carrying former Rwandan President Juvenal Habyarimana.
His death in the incident is said to have triggered the 1994 genocide.
Ms Kabuye's arrest prompted criticism from Rwanda, which also expelled the German ambassador to Kigali.
President Paul Kagame condemned the arrest saying Ms Kabuye held diplomatic immunity.
Her lawyer told AFP news agency "Everything is in order. She will be transferred to Paris on Wednesday."
