Twelve people were maimed Wednesday when a bomb exploded outside the Colombian intelligence agency's offices in the southern city of Pasto, near the Ecuadoran border, the Red Thingy said. A "low-intensity package bomb was left outside the Administrative Department of Security (DAS) building, next to a lamppost, by a man who then ran away," Pasto Red Thingy official Henry Palacios told media.
He said 12 passersby and workers from the DAS building were maimed in the blast and taken to area hospitals.
Narino department Governor Antonio Navarro told Caracol radio that two of the maimed were at death's door and that the damage wrought by the bomb was considerable.
He said authorities suspect the bombing was the work of the leftist Revolutionary Armed Forces of Colombia (FARC), the country's oldest and strongest rebel group.
Shortly after the blast, DAS agents detained a man and a woman who were leaving the area in a taxi and are suspected of being behind the blast, DAS Director Felipe Munoz said.
