ETA strikes again; luckily this time without hurting anyone:

A car bomb has exploded near the offices of a Basque television station in Bilbao in northern Spain.

The blast happened minutes after the building had been evacuated, following a warning call in the name of the Basque separatist group Eta.

Spanish media said there was structural damage to the building, but no casualties have been reported so far.

Started tweeting #bilbao, if you're interested. So far very few tweets yet.

UPDATE. Watch the explosion here.
