During the decade , with the beginning of the so-called , " strategy of tension " , the CGIL was the target of terrorist attack , perpetrated by neo-fascist groups . On 28 May 1978 , a bomb exploded during a trade union rally in Piazza della Loggia , Brescia , killing eight people and wounding more than one hundred . The bomb was placed inside a rubbish bin at the east end of the square . It was the beginning of the Years of Lead , a period of social and political turmoil that lasted from the late 1960s until the early 1980s , marked by a wave of both left-wing and right-wing political terrorism , which culminated with the kidnapping and murder of Christian democratic leader , Aldo Moro , in 1978 and Bologna railway station massacre in 1980
