Attorney General Cándido Conde Pumpido said on Wednesday that the prosecution office of the Spanish National Court would investigate "to the end" the alleged alliance between the Basque separatist group ETA and the Revolutionary Armed Forces of Colombia (FARC), a guerrilla group.

Conde Pumpido said that the Attorney General Office "supports" the measures that have been implemented based on the evidence found in the computer of Raúl Reyes, a FARC leader who was killed by the Colombian military. Such evidence presumably shows the ties between both terrorist groups, Efe reported.

The Spanish Attorney General apologized for not being able to express a more comprehensive opinion on the case, arguing that the issue is "sub judice" (under judicial consideration).

Eloy Velasco, a judge of the Spanish National Court, indicted several members of the Basque group ETA and of the rebel group FARC for their collaboration in a plot to kill several Colombian top officials, including President Álvaro Uribe. He also considered that there is evidence of "cooperation" of the Venezuelan government with the FARC-ETA alliance.

Conde Pumpido is in Brussels where the Spanish Presidency of the EU is advocating the creation of the European Attorney General, as provided for under the Treaty of Lisbon. The European Attorney General Office would help coordinate investigations into offences and frauds against the financial interests of the 27 member countries of the European Union.
