GOMA, Congo (AP) — While the international community is focused on the M23 rebellion, other armed groups have taken advantage of the security vacuum in eastern Congo, and killed over 260 people since April this year, a United Nations report said Wednesday.

“In April 2012, army desertions and the subsequent creation of the M23 armed group led the Congolese army to focus on efforts to contain this new rebellion. Many armed groups have taken advantage of the security vacuum left by the redeployment of army units to expand their own areas of influence,” said the report.
