Left-wing guerrillas from the National Liberation Army (ELN) in Colombia have claimed responsibility for a Friday morning attack against a pipeline used to transport crude to the country's most important refinery, located in the city of Barrancabermeja, APA reports quoting Reuters.
The attack resulted in an oil spill which affected surrounding vegetation and soil, the company said in a statement. A spokesman said that a fire that had broken out was later brought under control.
In a statement posted on one of its websites, the ELN said: "Our guerrilla forces carried out an act of sabotage on the La Cira Infantas pipeline used by Ecopetrol today, October 15, in the Paquistan region on the road between Barrancabermeja and Bucaramanga."
The group also took responsibility for attacks against the La Cira Infantas oil field in September, which resulted in production at some of the wells being halted.
