A caution sign marks the entrance gate to United Nations headquarters, where one day earlier a suicide bomber crashed through an adjacent exit gate and detonated a car full of explosives in the building's reception area, in Abuja, Nigeria Saturday, Aug. 27, 2011. Nigeria's president Goodluck Jonathan vowed Saturday to bring terrorism "under control" as he visited the bombed headquarters of the United Nations in his country, a day after at least 19 people died in an attack claimed by a radical Muslim sect.
