Rebels in eastern Democratic Republic of Congo have clashed with government troops and rival militias, cutting a vital link to the region’s main city, Goma. BBC News reports that M23 rebels have captured swathes of territory in mineral-rich North Kivu province since last year, advancing towards its capital, Goma. Police and local officials confirmed that the Tutsi-led group had cut off the road between Kitchanga and Goma. The fresh clashes come after the M23 was required to withdraw from territory it occupies, under the terms of regional mediation efforts.
