The FARC is Latin America's oldest rebel insurgency, and has been coming under increasing pressure from military attacks and growing desertions. It was once a 17,000-member force able to attack cities and kidnap almost at will. But it has been driven back into remote areas and now has about 9,000 combatants. The guerrillas have lost three major leaders this year. Listed as a terrorist group by U.S. and European officials, the FARC has used Colombia's cocaine trade to fund its operations.
