Diplomatic efforts are ongoing to put an end to the conflict in eastern DR Congo. What should have been a major breakthrough – the Congolese government meeting the M23 rebel group in the first direct negotiations – has now been on hold. At the last minute, the M23 pulled out. One of the reasons given is the new EU sanctions against several Rwandan officials over Rwanda’s alleged support for the M23 armed group. But DR Congo says it will attend peace talks in Luanda on Tuesday despite the snub.
