The Colombian armed forces say they have killed a senior commander of the Farc rebel group.
They said the guerrilla leader Sixto Cabana was among 27 rebels killed in an attack on a camp near the Ecuadorean border on Sunday.
Mr Cabana, 55, was wanted in the US for alleged cocaine trafficking and was on the Farc's ruling general staff.
The US had offered a reward of $2.5m (£1.6m) for information leading to his arrest.
The Colombian Defence Minister, Rodrigo Rivera, said it was the most grievous blow to the left-wing rebel group in recent years.
The fighting in the Putumayo region happened near the town of San Miguel, where eight policemen died in a rebel ambush earlier this month.
Police commandos were dropped by helicopter after air force planes bombed a rebel camp in the jungle.
