Colombia has offered to suspend the sentences of jailed guerrillas if rebels first free hostages including former presidential candidate Ingrid Betancourt, AP reported. Peace Commissioner Luis Carlos Restrepo said late Thursday that the liberation of some captives could jump-start the process of exchanging guerrillas for dozens of hostages, also including three U.S. defense contractors. «It is enough that Ingrid Betancourt be immediately freed for us to consider this humanitarian exchange is moving forward, and to begin delivering the benefits of suspended sentences to (jailed) members of the guerrilla group,» Restrepo told reporters. In return for the hostages' release, rebels would have to promise not to return to the ranks of the Revolutionary Armed Forces of Colombia, or FARC, which has been fighting for decades to topple the government.
