In the resulting M23 rebellion, M23 briefly captured the provincial capital of Goma in November 2012. Neighboring countries, particularly Rwanda, have been accused of arming rebels groups and using them as proxies to gain control of the resource-rich country, an accusation they deny. In March 2013, the United Nations Security Council authorized the United Nations Force Intervention Brigade to neutralize armed groups. On 5 November 2013, M23 declared an end to its insurgency.
