The Democratic Republic of Congo has asked for the extradition of rebel leader Gen Laurent Nkunda after his capture by neighbouring Rwanda. Gen Nkunda, who has led an ethnic Tutsi rebellion in the east since 2004, is wanted for atrocities allegedly committed by forces under his command. His arrest has been welcomed by the UN envoy to DR Congo. The UN's refugee agency has expressed alarm at moves to disarm a different rebel group - of ethnic Hutus. Gen Nkunda was arrested in Rwanda, after fleeing attempts to arrest him in eastern DR Congo by a joint military force from both countries. Correspondents say that it would appear that intense diplomacy has led to a deal under which DR Congo is letting Rwanda take action against its enemies - the Hutu rebels based in DR Congo - in return for taking out Gen Nkunda. If both groups are neutralised, peace in the region would become a realistic prospect. Some 4,000 Rwandan troops have entered DR Congo this week. The BBC's Thomas Fessy reports from the key east DR Congolese city of Goma that there is a sense of relief among residents there, who feel the war is nearing an end. Source: BBC
