Police and rescue workers stand in the debris of the premises of the United Nations House in Abuja on August 26, 2011 after it was hit by a bomb that killed at least 18 people, leaving others trapped and causing heavy damage. Some witnesses reported that the bomb exploded after a suspect rammed a car through the front gate. Parts of the first two floors of the building were blown out and rescue workers scrambled to rescue those left inside.
