Incident Summary:

11/24/2010: On Wednesday evening at 2000, in the rural area of La Hormiga, Valle del Guamuez, Putumayo, Colombia, militants detonated an unspecified amount of dynamite against the Transandino oil pipeline at kilometer 2. Although the attack resulted in no casualties, the oil pipeline sustained significant property damage from a fire that broke out after the explosion. Flames reaching up to 20 meters in height continued to flare through the next day on Thursday 11/25/2010. Furthermore, a large oil spill subsequently leaked into the Valle del Guamuez river, resulting in significant contamination to the public water supply of surrounding localities. No group claimed responsibility for the attack, but authorities suspected the Revolutionary Armed Forces of Colombia (FARC) was responsible.
