Rwandan-backed rebels are gaining ground in eastern Congo despite the unilateral ceasefire they declared earlier this week.

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.

M23 rebels claim they now control the Congolese city of Goma—an act Congo's government described as a 'declaration of war.'
