Trieste, Italy - Police are investigating local anarchist groups after three molotov cocktail bombs exploded outside a school that also serves as a polling station in Northern Italy. A fourth more serious bomb failed to explode. The attack came on the eve of a hotly contested national election.

Anarchists, who are ideologically opposed to all elected rulers, were responsible for intense rioting that left part of Milan's main shopping district destroyed a few weeks ago. The riot began in response to a march organized by an ultra right-wing fascist party that was running candidates in the election.
