The town councilors of the southwestern Colombian municipality of Garzon threatened Saturday to resign after an attack in which leftist guerrillas kidnapped one of their colleagues and killed a soldier, a police officer and two security guards.

The president of Garzon’s town council, Joselito Guevara, told local radio about the danger facing him and the other 14 local lawmakers and said they have drawn up a document expressing their concerns.

“The truth is that we don’t have (safety) guarantees,” Guevara said prior to a security council convened by regional authorities.

The meeting will be led by armed forces commander and interim Defense Minister Freddy Padilla de Leon, who traveled from Bogota to that town in Huila province.

Guevara said the abduction of his colleague, Armando Acuña, by Revolutionary Armed Forces of Colombia, or FARC, rebels demonstrates the need for President Alvaro Uribe’s government to provide municipal lawmakers with additional protective measures.

Acuña was kidnapped Friday in a FARC attack on a local government building in Garzon.

The rebels, who passed themselves off as soldiers, burst into the offices of the municipal government and the local courthouse and killed two guards and a police officer.

Later, a soldier who was inspecting the SUVs the guerrillas left abandoned near a mountainous area was killed when one of them exploded.

The FARC, which has fought a decades-old armed struggle against a succession of Colombian governments, funds its insurgency through the drug trade and kidnappings for ransom.

The rebel group once held some 60 high-value captives in hopes of swapping them for hundreds of jailed guerrillas, but the number of “exchangeables” is now down to about 20.

That group of “high-value” captives used to include numerous Colombian politicians, but the rebels have released some unilaterally and several more – including former presidential candidate Ingrid Betancourt – were rescued by the Colombian army in an elaborate ruse last summer.

The guerrillas released the last of the politicians on their list of “exchangeable” captives in early February.
