The Democratic Republic of Congo's government has rejected an ultimatum by M23 rebels to start talks, as rebels advance toward Goma, the main city in eastern Congo. Rwanda, which denies arming the rebels, has accused Congolese forces of firing into its territory.
The M23 rebel group began in April 2012 when several hundred men led by Gen Bosco Ntaganda, wanted by the International Criminal Court, defected from the Congo army. The group's name comes from a peace accord drawn up on March 23, 2009, between a now-defunct rebel group and government. - BBC, AP
