The Rwanda-backed armed group M23 vowed Thursday to "continue the march of liberation" to the DR Congo capital Kinshasa, as its fighters made further advances in the mineral-rich east of the country.

Their fury is focused on Rwandan President Paul Kagame, who they accuse of backing the rebels - an accusation long made by the UN. To put it bluntly, a group of UN experts maintains the Rwandan army is in "de facto control of M23 operations",

Much of the beleagured city of Goma was calm early Wednesday morning, after a day during which thousands of fleeing people hunkered down by roadsides as missiles flew and injured people streamed to overwhelmed hospitals.

KINSHASA/PARIS - France's foreign minister was due in Rwanda on Thursday after talks in the Democratic Republic of Congo as part of efforts to prevent a regional escalation following the capture of the eastern Congolese city of Goma by M23 rebels and Rwandan troops.

Rwanda, which diplomats say backs M23 fighters who seized Goma in Democratic Republic of Congo this week, called on Wednesday for a ceasefire across eastern Congo and for Congo to negotiate with the rebels while denying Rwandan troops were involved.
