BOGOTA - Colombia's FARC rebels freed 10 members of the armed forces held hostage in jungle prison camps for more than a decade on Monday, the last of a group the drug-funded group had used as bargaining chips to pressure the government. The four soldiers and six policemen were released to a humanitarian mission led by the International Committee of the Red Cross in what the Revolutionary Armed Forces of Colombia called a gesture of peace. Wearing olive fatigues and seeming well fed and relatively healthy, the 10 men stepped off a helicopter provided by Brazil after the Marxist rebels freed them in a remote area of southern Colombia. Smiling and joking with a medic, one soldier left the aircraft draped in the Colombian flag and skipping with joy. Each carried a plastic bag of belongings and one was accompanied by what appeared to be a small pig that had been his pet in the jungle. Another had what looked like a monkey on his shoulder. "To these victims of the intolerance and cruelty of the guerrillas, soldiers and policemen of Colombia, welcome to freedom," President Juan Manuel Santos said from the presidential palace. "Freedom has been long delayed, but now it's yours." The release could signal that the FARC is taking tentative steps toward a bid for talks that may end Latin America's oldest insurgency after five decades of killing and destroying economic infrastructure. But many Colombians remain skeptical that the guerrilla group, which is still believed to be holding as many as 700 civilian hostages for ransom, will lay down its weapons after having used previous peace talks to strengthen their forces. Santos, who is under pressure to end the conflict, has demanded the FARC free all its prisoners and cease attacks on civilian and military targets before any talks can take place. "As soon as the government considers there are sufficient conditions to initiate a process that would end the conflict, the country will know," Santos said, in an apparent response to rumors of secret peace talks. "In the meantime, everything else that has been said about this is no more than speculation." The 10 men were seized at the end of the 1990s when the FARC was at its strongest. They formed part of a group known as "canjeables," or exchangeables, used to pressure the government for political concessions rather than for ransom payments.
