(Reuters) -Rwandan-backed M23 rebels entered eastern Democratic Republic of Congo's second-largest city Bukavu on Friday, a rebel leader told Reuters, as residents reported seeing the militants in the streets of a northern district.

The Rwandan-backed rebels' entry into Bukavu follows their capture of Goma, defying international calls for a ceasefire.

The DRC government has repeatedly accused Rwanda of supporting the M23 rebel group, a claim that Rwanda denies. Kigali, in turn, alleges that Kinshasa collaborates with the Democratic Forces for the Liberation of Rwanda (FDLR), a Hutu armed group with ties to the perpetrators of the 1994 Rwandan genocide, an allegation the DRC rejects.
