While the M23 rebellion has monopolised the headlines on eastern
Democratic Republic of Congo (DRC) for over a year, a myriad of other
armed groups also operate in the region. They fight against the government or against other armed groups, in a series of often shifting alliances, and prey on the civilian population.
Here is a selection of some key forces:
M23: Army mutineers, for the most part Congolese Tutsi who speak the Rwandan language Kinyarwanda. Former rebels, they were integrated into the DRC army in 2009 but mutinied in April 2012, complaining that the peace deal had not been fully implemented. Kinshasa and the UN accuse the group of being backed by Rwanda and to a lesser extent by Uganda -- a charge denied by both Kigali and Kampala. M23 briefly seized and occupied Goma in November 2012 and recently resumed fighting against the Congolese army. The group's members have been fighting in the ranks of one force or another since the early 1990s. Estimating their number is difficult since an internal split resulted in many deaths and a wave of defections.
ALLIED DEMOCRATIC FORCES (ADF): Beginning as a group of Ugandan rebels opposed to the regime of President Yoweri Museveni, it has since also developed an Islamist agenda. Based in the Rwenzori mountains that straddle the Uganda/DR Congo border. Estimates as to their number vary from "several hundred to 1,300."
