Colombia Monday unveiled documents seized from guerrilla leader Raúl Reyes, who was killed last Saturday by the Colombian Army, which show an alliance, old contacts and even financial aid between the rebel Colombian Revolutionary Armed Forces (FARC) and Venezuelan President Hugo Chávez.

The documents were disclosed by General Oscar Naranjo, head of the Colombian National Police, in the Colombian government palace during a news conference.

The records include a letter from Luis Devia, alias Raúl Reyes, found in his computer. The letter stresses Chávez's gratefulness for some USD 50,000 the FARC gave him when he was in jail in 1992, after his failed coup d'etat, AP reported

According to Naranjo, the documents included a letter dated last February from commander Luciano Marín, alias Iván Márquez, a member of FARC Secretariat, to other colleagues. In the letter, Márquez talks about "Venezuela's financing to the FARC at USD 300 million."
