Over 2,000 bodies require burial in Goma after Rwanda-backed M23 rebels took over the Democratic Republic of Congo city last week, inflaming a decade-old conflict and humanitarian crisis, Congo's communications minister Patrick Muyaya said late on Monday.

The rebels continued advances in eastern Congo despite their own announcement of a cease-fire. The U.N. secretary-general called for them to lay down their guns and agree to mediation.

The M23 rebel group have captured the city of Goma in the eastern DRC in a major escalation of a drawn-out conflict.
