Well it seems like they apprehended 5 suspects of arabiaban origin earlier today. One of them had ties to the 9/11 attack so I guess it is all falling in place. As for those strong accusations against the ETA, well it' s all a publicity stunt right before the elections of this morning in Spain. Aznar is known for his 'fight against the ETA-terrorists' so it would do him good if he could play it in his benefit.
And it wasn' t Al-Qaida that claimed the attack but a splinter organisation with a dubious background.
Btw, isn' t Killzig of Basq origin? Or am I completely wrong on this one?
