Depends who was behind the attacks.
Well the ETA have an ongoing land claim in Spain and the Spanish were also supporters of the US's war on terrorism. Either way, an attack like this is sickening.
However, it was good to see all the Spanish people who queued up to donate some much needed blood after the bombs went off. Well played those people.
Apparently it was Al Qaeda... or so they say they did it. 😬
