Colombian rebels have attacked an oil field near the Venezuelan border.
The state-owned Ecopetrol said that no-one was injured in the attack on the Tibu field.
The left-wing Farc and the ELN are both active in the area, however the Colombian military did not specify which of the groups carried out the attack, which came after weeks of rebels targeting power stations, oil fields, pipelines and roads.
The latest attack comes a day after President Jose Manuel Santos was inaugurated for a second term.
