Bitter ethnic divisions develop in Rwanda in 1994, after the plane carrying President Juvénal Habyarimana was shot down over Kigali. In the space of 100 days, over 800,000 Rwandans were killed. Tonight, David Belton, former producer of BBC Newsnight, and Rwandan survivor Eric Murangwa Eugene discuss how the communities have been reconciled 20 years on. And whether or not the international community has learnt its lesson from its failure to react. Best available seating.
