The "Comandante Diego" Front of Colombia's second largest rebel group the ELN detonated explosives Jan. 1 at four crude-oil holding pools along the Caño Limon-Coveñas pipeline at Convención in the Norte de Santander department. A large blaze caused by the attacks created panic among the local population, who were forced to flee their homes, according to local media reports. Authorities are taking measures to prevent further environmental damage after the attacks, as well as reconstruct the damaged holding pools. The ELN  has been coordinating with the FARC in attacks on Colombia’s oil production infrastructure for the past few months, declaring war against multinational oil companies operating in the country last November. (Colombia Reports, Jan. 2; Radio Caracol, Jan. 1)
