Colombia's government announced that peace talks with Latin America's last major rebel army were resuming just hours after guerrillas killed 13 soldiers Saturday in an ambush, AP reported. The chief government negotiator said both sides would be back at the table on Monday morning. The Revolutionary Armed Forces of Colombia, or FARC, had announced a temporary freeze Friday over President Juan Manuel Santos' refusal to agree to a constitutional assembly and rewrite if a peace pact is struck. That followed Santos' Thursday announcement that he was asking Congress to schedule a referendum for next year, to coincide with national elections, on a peace agreement should it be attained.
