The Obama administration says Islamic militants in northern Nigeria are capitalizing on popular discontent with the government, and officials need to tackle economic problems if they are to stop the violence. An Easter Sunday bombing thought to have been carried out by Boko Haram killed at least 36 people.
U.S. Assistant Secretary of State for African Affairs Johnnie Carson says the threat from Boko Haram grows as Nigeria's standard of living declines.
