Police on Friday announced that a proclamation was included in the letter bomb sent
They announced that the manila envelope containing the bomb also contained a small roll of paper wrapped in insulating tape, which proved to be a proclamation claiming responsibility for the attack signed by the Italian organisation "Informal Anarchist Federation - International Network".
The proclamation was written in Italian and stated that the letter bomb was sent as a "show solidarity" with the jailed members of the Greek terror group "Conspiracy of Cells of Fire" and imprisoned 'comrades' in Chile, Switzerland and Germany.
