The Rwanda-backed rebels who captured eastern Congo 's key city of Goma sought to reassure its residents Thursday, holding a stadium rally and promising safety under their administration as they try to shore up public support amid growing international pressure.

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

Thousands fled the city of Goma on Monday as fighting raged between Congolese forces and rebels backed by neighboring Rwanda, who claimed to have captured eastern Congo’s largest regional hub.
