HAVANA: Colombia's government delegation to peace talks with leftist FARC rebels ruled out a ceasefire, as another round of negotiations ended in Havana.

The next one is scheduled to begin January 31. The goal is to end Latin America's longest-running guerrilla conflict, which has been under way since 1964.

This round of talks has centered on land reform, a key issue that gave rise to the war and stems from glaring inequalities between rich and poor in the Colombian countryside.

The two sides reported progress in a joint communique issued Thursday.

Before the talks started November 19, the rebels declared a unilateral ceasefire. They pressed the government to match it, but Bogota refused, citing previous negotiations a decade ago when a demilitarized zone set up by the government was allegedly used by the FARC to rearm and regroup.

The FARC ceasefire ended January 20.

The head of the government delegation to the current talks ruled out, again, a ceasefire by the army until, and unless, there are definitive peace accords.

"We want peace but not at any price," delegation chief Humberto de la Calle.

The other issues on the negotiating agenda are integrating guerrillas back into civil society, drug trafficking, the rights of victims of the war and how exactly to end hostilities.
