President Paul Kagame has warned France not to reopen an investigation into events that took place more than two decades ago. French investigators want to re-look at the cause of a plane crash in which Rwanda's president died back in 1994. It was one of the events that led to the genocide in which nearly a million people were killed. But current President Kagame says a fresh investigation will have consequences. CCTV's Jane Kiyo reports from Kigali.
