The Rwandan-backed armed group M23 moved south as it closed in on a key military airport in DR Congo on Friday, a day after pledging to take the capital Kinshasa and as international criticism mounted.

Rwanda-backed rebels who have captured eastern Congo’s largest city say they plan to take their rebellion to the capital and seek to gain political power

Their fury is focused on Rwandan President Paul Kagame, who they accuse of backing the rebels - an accusation long made by the UN. To put it bluntly, a group of UN experts maintains the Rwandan army is in "de facto control of M23 operations",

The Rwanda-backed armed group M23 vowed on Thursday to march on the DR Congo capital, Kinshasa, as its fighters made further advances in the mineral-rich east of the country.

The rebels were advancing toward the center of South Kivu province after capturing several of its towns, including Kalungu, Kanyezire and Mukwinja, according to a local civil society leader and an aid worker in the area who spoke on condition of anonymity because they were not authorized to speak on the matter publicly.
