[rant on] Shee-it... they need to start retaliation by decimation... for every one Spaniard, American, and/or other allies of the USA, 10 (or more) suspected terrorists will pay with their lives. Need to give some hostile villages and countries some B-52 urban renewal! Al-Qaeda whacked over 3000 on 9/11/01, payback's 30,000 (give or take a few thousand
) of 'em!

Doesn't look like it's the work of the 'ETArras' (what the Spaniards call members of ETA); like the IRA, they like to call in a coded warning that a bomb's about to go off, usually allowing for just enough time for cops to clear the streets of bystanders. It could be a splinter cell of ETA for all we know, or even World Enemy #1 Al-Qaeda.
