The mineral-rich east of the Democratic Republic of Congo has been dogged by conflict for more than 30 years, since the 1994 Rwandan genocide. Violence has once again seen an uptick in recent months as the M23 rebel group has captured a number of key cities and towns. Led by ethnic Tutsis, the militia has long been associated with the Rwandan government by the UN and others, but President Paul Kagame has consistently dismissed the links. But, as international attention on the humanitarian situation in the eastern DRC grows, is this a line he can sustain?

On this episode, Jonny Dymond is joined by the BBC's Deputy Africa Editor, Anne Soy. They track the origins of the conflict, and consider the incentive behind Rwanda's alleged involvement.
