A Rwandan sought by Kigali for his alleged role in the 1994 genocide will contest a Danish extradition ruling in the European Court of Human Rights, his lawyer said Thursday.

Emmanuel Mbarushimana, 51, appealed the Wednesday decision by Denmark's Supreme Court to extradite him to Rwanda on the grounds that he won't get a fair trial there, his lawyer Bjoern Elmqvist said.

The United States indicated Wednesday it was ready to lift sanctions against Rwanda if Kigali cuts all ties with Congolese M23 rebels.

Washington has distanced itself from its ally Rwanda since July 2012 by freezing its modest $200,000 military aid and imposed sanctions in a bid to urge President Paul Kagame's regime to end its support of the mainly Tutsi rebels of M23, who surrendered on Tuesday.

Democratic Republic of Congo President Joseph Kabila on Wednesday condemned the "never-ending aggression" by neighboring Rwanda in a speech at the U.N. General Assembly.

Rwanda's President Paul Kagame was also due to appear before world leaders at the assembly amid international concern over new fighting in eastern DR Congo.

A grenade attack at a Kigali market claimed a second victim Saturday as Rwanda prepared for legislative polls predicted to bolster the ruling party of President Paul Kagame.

Two grenades were used in an attack at a market on Friday that had killed one person and left 14 wounded. One of the devices had failed to explode and remained undetected.

Christina Aguilera says that although she went to Rwanda to help others, she ended up helping herself.

The 32-year-old singer visited Rwanda in June for a hunger relief effort. She said the experience helped her ground herself.

U.N. leader Ban Ki-moon said Friday that Democratic Republic of Congo rebels have fired shells into neighboring Rwanda, launching into a dispute that has heightened tensions between the two neighbors.

Ban also said "spoilers" encouraging mounting violence in eastern DR Congo must be held to account but he did not follow other U.N. officials in naming Rwanda as a backer of the rebels.

Kinshasa has issued international arrest warrants for four leaders of the Congolese rebel group M23 who have found shelter in Rwanda, the government spokesman said Friday.

The Democratic Republic of Congo issued the warrants on Thursday against the four, who have also been slapped with sanctions by the United Nations, Lambert Mende said in a statement.

The U.N. peacekeeping mission in DR Congo (MONUSCO) on Wednesday denied accusations that it shelled Rwandan villages in recent clashes between the Congolese army and M23 rebels.

General Joseph Nzabamwita of the Rwandan army charged Monday that MONUSCO troops had "deliberately" targeted two villages, claiming that two shells, which landed without harming inhabitants, were nonetheless a "deliberate provocation".

French police have arrested a former Rwandan colonel wanted for his alleged role in the east African nation's 1994 genocide, his lawyer said Saturday.

Laurent Serubuga, around 75 years old, was apprehended near the northern French city of Cambrai on Thursday under an international arrest warrant issued by Rwanda, lawyer Thierry Massis said.

Rwanda is key to ensuring peace in the volatile eastern Democratic Republic of Congo, U.N. chief Ban Ki-moon said Friday as he toured the region to boost a new deal to end decades of violence.

A United Nations-brokered accord, signed in February by 11 regional countries after a bloody uprising by Congo's M23 rebels, seeks to quell a long-running conflict in mineral-rich eastern Congo, which neighbors Rwanda.
