According to Reuters a military source credits the early Sunday morning attack to the dominant rebebl group FARC, which was also targeting oil and gas pipelines.
While exports can continue due to the use of stockpiles, Cerrejon spokesman Juan Carlos Restrepo reportedly said it was unclear how long it would take to reopen the mine’s rail line.
"Cerrejon condemns this type of violent action that generates considerable economic and environmental damage and at the same time creates a high risk of fatalities," Cerrejon reportedly said.
Cerrejon, equally owned BHP Billiton, Anglo American and Glencore Xstrata, recently said it was just 1% short of its production target of 34 million tonnes for 2013.
The forecast was made despite a month-long strike that ended in March, previous guerrilla attacks, weaker coal prices and some adverse weather.
