Bomb explodes outside Colombian police station General Rodolfo Palomino, the national police director of citizen security, blamed the leftist Revolutionary Armed Forces of Colombia, or FARC, for the attack, The southwestern port is one of Colombia's most lawless cities, a cocaine-smuggling hub where leftist rebels, right-wing criminal bands and drug traffickers are all present. The 1:58 p.m. blast occurred "in an area with a great abundance of population, as much for the hour as the geographical location," Gen Palomino said. It is the end of lunch hour in Colombia. Tumaco is in Narino state, which borders Ecuador and is laced with dozens of rivers popular with drug traffickers, who include the FARC. The most recent major FARC attack in the region occurred in October when 10 soldiers were killed in a mortar attack while on patrol in a rural part of Tumaco.
