Just this morning a bomb went off outside the Socialist Party offices in Bilbao, slightly wounding seven policemen. http://news.bbc.co.uk/2/hi/in_depth/7351900.stm
The attacks are being blamed on ETA, who last month murdered a socialist councillor.
It's an ominous beginning for Spain's new parliament, headed by Zapatero and the socialists. Further highlighting Zap's misjudgement in getting into bed with ETA in the first place, it strengthens the hand of the right-wing parties and thus weakens any chance of peace.
