The militant Islamist group Boko Haram may be planning an attack on U.S. interests in Nigeria, said U.S. intelligence and counterterrorism officials, speaking with NBC News on condition of anonymity. The officials declined to characterize the nature of the evidence, other than to say it was recent and non-specific. They said the group's desire to strike against a U.S. target apparently has been heightened by the increasing U.S. involvement in the hunt for 276 missing Nigerian schoolgirls abducted by the group last month, though the goal itself is not new.
