Two trucks and a crane belonging to the Canadian oil company Gran Tierra Energy were burned up by FARC guerrillas on a highway in the southern province of Caqueta, the Colombian army said Friday.

The attack occurred Thursday at a roadblock set up by the guerrilla group in the municipality of San Jose del Fragua, the army's 12th Brigade said in a statement.

"From the minute we received information about the illegal roadblock, we began a special troop movement in order to quickly counteract it and avoid greater damage. That way we avoided having more vehicles destroyed," the military unit said.

The army attributed the attack to the 49th Front of the Revolutionary Armed Forces of Colombia, or FARC, and said that such actions "undermine regional development, jobs, mobility and the economic infrastructure" of the country. EFE
