E.T.A. is a terrorist organization in

ETA, short for Euskadi ta Askatasuna (Basque Homeland and Freedom), is a Basque separatist organization that operated in the Basque region of Spain. The group pursued an independent Basque homeland and used violent means, leading to its classification as a terrorist organization by various agencies; its activities are tied to the Basque secessionist movement within Spain [1]. Spanish politics has long contended with Basque regionalist and secessionist pressures, and ETA was the most prominent armed group associated with that struggle. Given this background, ETA is correctly identified as a terrorist organization in Spain, not Cyprus, Sri Lanka, or South Africa [1].
