Thérèse Kayikwamba Wagner said this followed decades of impunity and failure to hold Rwandan President Paul Kagame accountable for violating international law.

The Rwandan-backed armed group M23 moved south as it closed in on a key military airport in DR Congo on Friday, a day after pledging to take the capital Kinshasa and as international criticism mounted.
