Founded in 1959 with the aim of establishing an independent homeland based on Marxist principles in the northern Spanish Provinces of Vizcaya, Guipuzcoa, Alava, and Navarra, and the southwestern French Departments of Labourd, Basse-Navarra, and Soule.
Primarily involved in bombings and assassinations of Spanish Government officials, security and military forces, politicians, and judicial figures. ETA finances its activities through kidnappings, robberies, and extortion. The group has killed more than 800 persons and injured hundreds of others since it began lethal attacks in the early 1960s. In November 1999, ETA broke its "unilateral and indefinite" cease-fire and began an assassination and bombing campaign that has killed 38 individuals and wounded scores more by the end of 2001.
Unknown; may have hundreds of members, plus supporters.
Operates primarily in the Basque autonomous regions of northern Spain and southwestern France, but also has bombed Spanish and French interests elsewhere.
Has received training at various times in the past in Libya, Lebanon, and Nicaragua. Some ETA members allegedly have received sanctuary in Cuba while others reside in South America.
