While the claim specifies a quote from Cauca Governor Octavio Guzmán regarding the location (Pan-American Highway, El Túnel sector of Cajibedo) and nature of the attack, the provided evidence only contains general information about the Cauca Department and does not independently corroborate the specific statement attributed to the governor in the manner required for a higher verdict.

The evidence provided for this claim is limited to general information about Cauca and Colombian politics (Wikipedia entries on elections and FARC). There is no independent corroboration in the gathered evidence to confirm that Governor Guzmán specifically stated that the Minister of Defense Pedro Sáanchez was at the scene to coordinate rescue efforts.

The evidence provided for this claim consists only of general web search results related to fertilizers and do not contain any information regarding the governor stating that authorities are initiating a national-level security council.

While the web search results confirm that General Commander Hugo Alejandro López Barreto made statements regarding a 'wave of attacks' and mentioned various locations, the specific list of locations (El Tambo, Calopón, etc.) and the exact attribution to López Barreto in the provided evidence is not independently corroborated by a second distinct news source.

The web search results confirm the existence of the FARC and its conflict history, and the claim mentions the dissident factions and Néstor Gregorio Vera Fernández ('Iván Mordisco'). However, the specific attribution of blaming the bombing on these dissident factions by the Colombian Armed Forces is not corroborated by a second independent news source in the provided evidence.
