Former FDLR fighters are first sent to the Mutobo demobilization camp, where they stay for three months. The camp is where Nizyimani has started his return to civilian society.

Former child soldiers are then sent to a rehabilitation center where they meet with mental health experts and receive medical testing. The former soldiers begin studying again. And efforts are made to find their relatives.

But, sadly, that is not all of what is happening. Dee Brillenburg Wurth heads MONUSCO’s child protection section in Kinshasa. While Rwanda is working to help its own children come home, she says the country is also systematically recruiting children to work for the M23.

MONUSCO cannot work outside of Congo. But Ms. Brillenburg Wurth says the group has evidence from witnesses that Rwanda is actively pressing children into service.

“We know from children -- and this is corroborated by other children and by adults -- that children are being recruited. For example, we had an example of a football coach, of a police officer. At the beginning they told us they had this system in place, $5 for every child that was recruited.”

She says 122 children were questioned. Of those, 37 were Rwandan. Some were recruited in their country. Others were recruited in Congo. Some thought they were being asked to join the Rwandan army. Others did not even know they were in the DRC.

Ms. Brillenburg Wurth says children were often taken from their villages. Many of the children started life as an M23 child carrying supplies from the Rwandan border.
