Colombian radio Caracol says leftist rebels have announced they will liberate three hostages, all held for more than six years, because of health problems.

In a statement reprinted on the radio station's web site on Sunday, rebels from the Revolutionary Armed Forces of Colombia, or FARC, said they would release three politicians, Gloria Polanco, Luis Eladio Perez and Orlando Beltran, all kidnapped in 2001.

Without putting a date on their liberation, the FARC said that it would like to free the hostages to Venezuelan President Hugo Chavez or a delegate chosen by him.
