For more than a year and a half, a series of massacres - which have never been claimed - have been committed in the Beni region in the east of the Democratic Republic of Congo. More than 700 people have died in attacks on civilians in the region neighbouring Uganda, according to the United Nations.
The Congolese army regularly announces military operations against the Ugandan Islamist rebels of the ADF (Allied Democratic Forces), but the rebels have never been completely expelled from the territory.
The ADF has been active in DRC for more than two decades and stands accused of a litany of human rights abuses, as well as being involved with criminal networks funded by kidnappings and smuggling.
The Congolese army is also supported by 3,000 MONUSCO troops, the UN's largest mission in the world.
Our reporters went to investigate these brutal mass killings in eastern DR Congo. Our team looked at what is preventing the armed forces from protecting Beni’s citizens. Is there collusion between the Congolese army and the rebels? Why have UN forces failed in their mission to protect civilians?
