HAVANA (Reuters) - Colombia and Marxist-led FARC rebels reported important advances on Friday on the critical issue of agrarian reform in their talks to end half a century of war but the government complained the negotiations were still moving too slowly.
The rebels also put a possible chill in the process by rejecting the notion of legal prosecution for their actions in the conflict, which has left thousands of people dead and millions displaced.
The statements came at the end of the latest round of peace negotiations, which began in November and have yet to produce an accord on agrarian reform, the first of five points on their agenda.
"There were important advances in this round of talks toward the construction of new agreements," the two sides said in a joint communique. They added that they had a draft agreement in hand on the agrarian issue, which includes distribution of land and rural development.
But lead government negotiator Humberto de la Calle told reporters "the pace of the conversations has been insufficient, inconstant."
"We could have progressed much more," said the former Colombian vice president.
Conversely, Ivan Marquez, lead negotiator for the FARC, or Revolutionary Armed Forces of Colombia, said his team was pleased at how far they had come.
"We're advancing. The peace delegation of the FARC feels satisfied with the gains we are making," the bearded, bespectacled guerrilla told reporters outside the Havana convention center where the talks are being held.
The government and rebels are trying to end a war that dates to 1964 when the FARC was formed as a communist agrarian reform movement to fight Colombia's long history of social inequality and concentrated land ownership.
The rebels have proposed giving 20 million hectares (49.4 million acres) of land to the poor and limiting how much property big landowners can have.
The government has insisted no land will be taken from private landowners, but acknowledged that rural development and distribution of land are key to achieving peace.
MORE ISSUES LOOM
Should they get final agreement on the issue, they can move on to the others, which include compensation for war victims, ending the conflict, drug trafficking that has funded rebel activities and the political and legal status of the FARC members.
Many Colombians feel that the rebels must face justice for war casualties, the use of kidnappings to extort money and involvement in the illicit drug trade, the latter a charge the rebels have denied.
Talks insiders have said the question of punishment for FARC leaders will be one of the most difficult agenda points.
In a strongly worded statement, the rebels said they would be willing only to "review" any "error" committed during the war but ruled out prosecution by a state they said they had legitimately risen up against for persecuting and neglecting its own people.
"A state that has suppressed so many human beings in a heartless manner with its economic policy must beg for forgiveness," the group said. "The assassins and their tribunals have no moral authority to judge us."
Colombian President Juan Manuel Santos, who has said he wants the peace process finished this year, applied pressure on Friday by ordering the military to step up actions against the rebels.
"They must listen there in Cuba," he said at a public event. "Here we are offering that they change bullets for votes, and that they change them rapidly because we are going to continue with this pressure in all the national territory."
Santos initiated the peace talks and is pushing to finish them on a bet the FARC had been so weakened by the government's 10-year, U.S.-backed offensive that its leaders are ready to negotiate an end to the fighting.
Three previous peace attempts, the last ending in 2002, have failed to end Latin America's longest running rebel insurgency.
The rebels, estimated to number 8,000, have been pushed into remote corners of the country but are still able to attack oil and mining operations that are fueling Colombia's economic growth.
Santos said 11 rebels had surrendered to authorities on Friday, which he called an "important event."
The peace talks, in which Norway and Cuba are serving as guarantors, are expected to resume May 15, a government spokesman said.
