ATHENS (Reuters) - Greek police searched the offices of the Golden Dawn party on Wednesday after an anti-racism rapper was stabbed to death by a man who sympathised with the far-right group.

The killing touched a nerve in Greece, where an economic crisis has worsened social tensions, and rallies in several cities to mark the death turned violent.
