It's ETA. Otegi (leader of the political branch) may say whatever he wants. For what I've heard, there's already at least one member of ETA recognized in the video recordings of the Alcala Train Station.
they're a bunch of sucking bastards, and make no mistake, they don't target political heads, they target whoever gets into their path. Last week a member of ETA was stopped by the spanish police with a 500kg bomb. HALF A TON of industrial explosives, they were going to be put in front of a bus station.
173 dead. 500 wounded. Still counting.
Worse ****ing terrorist attack in spanish history. As a basque, I feel ashamed of those sons of a ***** who were born in my native land.
P.D. CNN may call ETA "separatist group"...you see this, so you can see they are no separatists. They are a ****ing group of terrorist sonofa*****es.
