I had not heard about this, mostly because I've been busy and not reading much news.
But why should this be all over the news? Has the ETA ever carried out an attack on the USA? no. Has the ETA ever carried out an attack outside of Spain? No, at least none that I can find.
According to this: http://en.wikipedia.org/wiki/List_of_ETA_attacks
the ETA carried out about 2 dozen attacks before 9/11/01 and nearly a dozen since, and there has been hardly any reporting on any of these in the international press. Is this because they aren't Muslins so no one cares? No, it's because the ETA's attacks are a Spanish problem that has had little effect on the rest of the world, and should be left to the Spanish athorities to deal with unless they ask for outside help.
