Colombia's largest coal miner, Cerrejon, said Feb. 24 that rebels broke into its facility at Mina Sur, La Guajira department, and burned four of the company's trucks in what it called a "terrorist attack." The attack came four days after the company declared force majeure in the face of work stoppage that began on Feb. 7. Cerrejon, a joint venture between Anglo American, BHP Billiton and Xstrata, operates Colombia's largest open-pit mine, and has frequently been the target of guerilla attacks. Both the FARC and ELN guerilla groups operate in the zone. In 2012, Cerrejon produced around 34.6 million tons of coal, half of which was exported to Europe.
