A bomb damaged a section of Colombia’s Cano Limon pipeline on Friday, state-run oil company Ecopetrol said, causing a crude oil spill around the site of the explosion.

The bombing, the eighteenth on the pipeline this year, occurred in the rural municipality of Saravena, in the province of Arauca near the border with Venezuela.
