In the eastern Democratic Republic of Congo, the M23 rebel group has handed over an important military base to an East African regional force.
Rumangabo Camp, north of the city of Goma, was seized last October but was handed over as part of a ceasefire brokered by East African leaders.
However, M23 fighters have still been seen in the Kibumba area, despite the fact that it was also meant to have been handed over last month.
At least 400,000 people were displaced last year during an offensive by the group.
The Congolese government and UN experts say Rwanda is supporting M23 – which Kigali denies.
