Three small bombs exploded outside an Athens police station in the pre-dawn hours May 5 raising concerns about security for the Olympic Games August 13-29. Evidence indicates that the blasts were the work of small local anarchist groups that regularly stage small bomb attacks around the city, and the timing, 100 days before the opening of the games, suggests they were trying to make a statement. The Greek government played down the blasts as unrelated to preparations for the Olympics, but local police, the apparent targets of the attack, said there was cause for concern.
