Thirteen Colombian leftist guerrillas were killed in an airstrike in the southwestern part of the country, the defence ministry said Tuesday.
Monday's attack targeted a camp of the Revolutionary Armed Forces of Colombia (FARC) outside the Ipiales town near the border with Ecuador.
Army troops and police commandos entered the camp after the bombing and found the bodies of 13 rebels. Two wounded rebels were arrested. The operation was carried out after a tip-off from the police.
Five rifles, a machine gun, a grenade launcher and other weapons and documents were seized.
About 35 fighters from the FARC's 48th Front were in the camp at the time of the attack. Security forces have launched a search to capture the rebels who fled the camp.
