The brutal Boko Haram rebels are gaining ground at a frightening pace in northwest Nigeria, even mounting a bloody attack this week on the region's major city, Maiduguri. Reports are mounting that the exremist movement is funding its insurgency by exploiting Nigeria's strategic place as a crossroads of the global narco-traffick. BBC News on Jan. 25 asked "How have Nigeria's militants become so strong?" It cited the findings of the International Crisis Group that Boko Haram "has forged ties with arms smugglers in the lawless parts of the vast Sahel region." Plenty of its arms (including tanks and armored vehicles) have been plundered from the Nigerian army itself. But plenty more are thought to have come from Libya, where arms depots were looted when Moammar Qaddafi's regime was overthrown in 2011. Trafficking networks have been moving that plundered war material across the Sahel and Sahara, integrating the traffick into routes already established for moving drugs and other contraband between West Africa, Europe and Asia.
