Info on a related incident was leaked to wikileaks too. http://wikileaks.org/cable/2006/07/06BRASILIA1511.html

> In a decision taken and kept in secret, the Brazilian National Committee on Refuges (CONARE) July 14 granted political refugee status to Francisco Antonio Cadena Collazos (known in Brazil as Olivera Medina), the so-called Ambassador to Brazil of the FARC (Revolutionary Armed Forces of Colombia), who was arrested in Brazil in August 2005 at the request of Interpol, based on a Colombian arrest warrant which included charges of murder for terrorist purposes, kidnapping, extortion and terrorism.

Being in the media is not any kind of proof, specially the media you just cited.

The second link has a transcription of the FARC website. It's not a rumour, FARC used to be present in the Foro de Sao Paulo meetings. But of course you're free to reject any evidence you want.
