The battle for control in Democratic Republic of the Congo (DRC) is coming to a head as the country prepares for a presidential vote in late 2016. Eastern regions of the DRC are still at the mercy of armed groups and the Congolese armed forces, who have all been accused of committing serious abuses against civilians.
The rebel M23 group was defeated in eastern DRC in late 2013, after a 20-month campaign led by the Congolese army and backed by thousands of UN fighters, but civilians are still living in fear of sexual violence, kidnappings and killings. Conflict rages over control of land, mineral resources, and ethnic division.
In this series, IBTimes UK takes a closer look at the armed groups fighting in the eastern regions of South and North Kivu.
