One person was killed and three others were wounded in an attack by FARC guerrillas on a town in southwestern Colombia, the army said.

Revolutionary Armed Forces of Colombia, or FARC, guerrillas threw explosive charges Saturday at dwellings in Caloto, a village in Cauca province, 14th Mobile Brigade spokesman Col. Jhon Meza said.

The FARC, which is holding peace talks with the Colombian government, declared a unilateral cease-fire from Nov. 20 to Jan. 20.

The cease-fire was confirmed by the FARC's negotiating team, which is holding talks with government representatives in Havana.

There have been no clashes between army troops operating in the area and FARC units, Meza said.

The accord establishing a framework for the peace process was signed on Aug. 26 in Havana after six months of secret exploratory discussions on the communist-ruled island under the auspices of the Cuban and Norwegian governments.

The initial phase of the talks began on Nov. 19.

The most recent peace process with the rebels, during the 1998-2002 government of President Andres Pastrana, took place in a demilitarized area of southern Colombia - dubbed "Farclandia" - and collapsed amid mutual recriminations.

The FARC has battled a succession of Colombian governments since 1964. The insurgency swelled to nearly 20,000 fighters in the early 2000s, but now numbers around 8,500 combatants.

Colombia's armed forces, bolstered by billions of dollars of aid from the United States, have scored dramatic successes against the FARC in recent years, but the rebels remain capable of inflicting significant damage on the military and on vulnerable infrastructure. EFE
