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.1 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.
