(Reuters) – Colombia’s government and leftist FARC rebels signed a historic ceasefire deal on Thursday that brought them tantalizingly close to ending the longest running conflict in the Americas. The accord, capping three years of peace talks in Cuba, sparked celebrations and tears of happiness among some in the Colombian capital. It sets the stage for a final deal to end a guerrilla war born in the 1960s out of frustration with deep socio-economic inequalities that outlived all other major uprisings in Latin America.
