Colombia's FARC guerillas may be working under the table with their supposed bitter enemies in the ultra-right paramilitary groups. E-mails released by authorities on Aug. 5 reportededly reveal that the FARC and Los Urabeños paramilitary have been collaborating to traffic drugs and weapons. In one of the undated e-mails, a FARC fighter known as "Ruben Manteco" wrote to "Pastor Alape"—one of the FARC's top commanders and a representative in Havana for peace talks with the Colombian government. The message refers to a gift offered the FARC by "Otoniel," the notorious Urabeño warlord. According to the e-mail exchange, Otoniel sent $170,000 as a good-will gesture to prove his reliability as a business partner. Alape instructed Manteco to accept the gift, adding that he should pursue negotiations on arms deals once confidence in the partnership was established. Another e-mail exchange discusses plans for FARC-Urabeño collaboration in drug trafficking. In that exchange, "Roman Ruiz," a FARC commander who was killed in a Colombian army offensive earlier this year, suggests to Alape that the guerrillas raise the price on cocaine exports. Other e-mails indicate the FARC has been providing security to the Urabeños during their drug operations while also helping to broker deals.
