BOGOTA, July 6 (Reuters) - Ivan Marquez, the well-known leader of a faction of former FARC rebels who returned to arms after a peace deal with Colombia's government, has died in Venezuela, two sources familiar with the matter told Reuters on Thursday.
The attack against Marquez, whose real name was Luciano Marín Arango, may have been led by Ivan Mordisco, leader of a rival FARC dissident group, according to security sources.
Colombia's Defense Minister Ivan Velasquez told journalists there was still no official information on Marquez's death.
Marquez later emerged as the leader of the so-called Segunda Marquetalia, a group of former FARC who took up arms anew.
Petro reopened diplomatic and trade relations with Venezuela and Venezuela is a guarantor at Colombia's peace talks with the National Liberation Army rebels.
