Rebels in the Central African Republic vowed to step up attacks over the support they say the government is getting from Russia in return for resources in the diamond-rich country, fueling fears of a return to full-blown conflict in one of the world’s least developed countries. Bloomberg reports that a loose alliance of six rebel groups called the Coalition of Patriots for Change ambushed the capital, Bangui, last week, firing rocket-propelled grenades at foreign forces. The attack was meant as a warning to Touadera’s government to stop the “organized pillaging by Russian mercenaries,” Abakar Sabone, a military spokesman for the alliance and former tourism minister, said by phone. “If Touadera wants peace we’re ready, and if he wants war we’re equally ready,” he said.
