The United Nations Security Council on Sunday demanded that M23 rebel forces stop an ongoing offensive and advance towards Goma, the largest city in eastern Democratic Republic of Congo, and that "external forces" in the region immediately withdraw.

Rwandan-backed rebels captured the city of Goma in eastern Congo early Monday, according to a press release by the M23 rebel movement. The city's capture came following a 48-hour deadline imposed by the group for the Congolese army to surrender their weapons.
