The leader of Colombia's FARC rebel group, Rodrigo Londono, suffered a stroke and has been admitted to the hospital in "satisfactory" condition, doctors at the clinic said on Sunday.

Londono, 58, who goes by the nom de guerre "Timochenko" is awake and alert after being admitted to a university hospital in the city of Villavicencio in central Colombia, according to the director of the facility, Lydis Herrera.

His stroke occurred just days after the FARC -- short for the Revolutionary Armed Forces of Colombia -- declared it had finished the process of disarming, effectively dismantling Latin America's oldest armed guerrilla force after more than a half-century of civil war.
