The United Nations has accused Rwanda of having lent aid to the M23 rebel movement in the eastern part of DR Congo. After mutinying from the DRC army in April, subsequent fighting between the forces led to the displacement of 200,000 people.
Rwanda has denied that they are helping the Congolese rebels.
Of greater concern is that Rwandan president Paul Kagame appears to be losing favor with western nations. Indeed, the Dutch foreign ministry has warned that unless it receives assurances from the Rwandan government that it is not supporting the rebels, they will confer with other European nations and consider taking similar action against Kigali.
