On August 26, 2011, a suicide bomber drove a vehicle borne improvised explosive device (VBIED) into the United Nations (U.N.) headquarters in Abuja, Nigeria, killing 23 people and injuring more than 80 others Responsibility for the bombing, one of the deadliest in the United Nations' history, was claimed by Boko Haram, an Islamist religious sect turned insurgent group based in the predominantly Muslim northern Nigeria. While this attack occurred inside Nigerian borders, it was the first time Boko Haram had targeted an international, non-Nigerian entity. The attack marked a significant shift in the targeting and goals of the group, largely unknown to the U.S. Intelligence Community, and capped off an evolution in the capabilities of Boko Haram, beginning in the mid-2000s, from attacks with poisoned arrows and machetes to sophisticated car bombings. In a video that surfaced in Nigeria in the weeks following the U.N. bombing, the perpetrator of the attack described the U.N. as a forum for "all global evil" and stated the attacks were designed to "send a message to the U.S. President and 'other infidels.'" According to Ambassador Anthony Holmes, Deputy to the Commander for Civil- Military Activities (DCMA) of United States Africa Command (AFRICOM), members of Boko Haram are being trained by Al Qaeda in the Lands of the Islamic Maghreb (AQIM). They are also believed to have ties to the Somalian militant group al Shabaab. This cooperation, combined with the increased sophistication of attacks executed by Boko Haram, have led to concerns from the U.S. Intelligence Community over the sect's intent and capability to strike Western targets in Nigeria, throughout Africa, and most importantly, the U.S. Homeland. Historically, Boko Haram has been focused on Nigerian government targets. Until recently, Western intelligence services did not widely view Boko Haram as a potential threat. Even after the U.N. attack, Nigerian experts remain skeptical about Boko Haram's intent and capability to strike U.S. interests and the homeland.
