On 12 December 1969, people belonging to or sympathizing for Ordine Nuovo placed a bomb in Piazza Fontana in Milan, killing 16 and wounding 90. This bombing marked the beginning of the "strategy of tension" in Italy. "Ordine Nuovo" member Delfo Zorzi was among those convicted for the crime on June 20, 2001, together with Carlo Maria Maggi and Giancarlo Rognoni, but all were later found not guilty in 2004.
