A leader of Colombia’s smaller rebel group has been released from prison today in hopes that he will be able to persuade his fellow guerrillas to hold peace talks.

Colombian guerrillas have said they would be prepared to consider an exchange of seven hostages for rebels held in prison, it was reported today.

A senior Roman Catholic Church leader met with imprisoned leaders of Colombia’s second-largest rebel group as part of stepped up efforts to secure the release of seven foreign hostages.
