The groups comprising the Informal Anarchist Federation are the "July 20th Brigade," the "Five Cs," "International Solidarity" and the "Cooperative of Hand-Made Fire & Related Items." Each of these groups has also forged its own set of alliances outside of the FAI.
The group has three suspected members imprisoned in Spain, which may explain the Spanish focus of the threatened target list.
Alleged leaders Giovanni Barcia and Claudio Lavazza are in prison at Huelva in southern Spain for the murder of two policemen during a bank robbery in 1996 in Cordoba, Spain. Barcia was later transferred to a prison in Almeria. Both are serving 50-year sentences.
A third suspected member was convicted of robbery in the same incident; Michele Pontolillo was sent to Villabona prison in the Asturias region.
