A Chequer-Board of Nights and Days

High-ranking officials in Venezuela offered to help Colombian guerrillas obtain surface-to-air missiles meant to change the balance of power in their war with the Colombian government, according to internal rebel documents.

Venezuelan officials served as middlemen with Australian arms dealers and agreed to help the rebel commanders travel to the Middle East to receive missile training, according to files on computer hard drives seized by Colombian authorities and shown to The Washington Post. In interviews, Colombian officials said they have no evidence that the guerrillas obtained the antiaircraft missiles but added that Venezuelan authorities appear to have provided light arms, thousands of rounds of ammunition and rocket-propelled grenade launchers.

The disclosures have already started to reverberate in the Bush administration and among Latin America policymakers on Capitol Hill, where a small group of Republicans has proposed classifying Venezuela, a major oil exporter to the United States, as a state sponsor of terrorism. The United States and Europe long ago blacklisted the rebel organization, the Revolutionary Armed Forces of Colombia, or FARC, as a terrorist group.
