The earliest post-war activism for South Tyrol 's removal from Italy can be found in the South Tyrolean Liberation Committee , which conducted bombings of Italian infrastructure and fascist monuments primarily between the mid-1950s and 1961 . The most notable of these incidents was the Night of Fire on June 12 , 1961 , in which a large electrical supply unit was destroyed via explosives . The incident was followed by a series of bombings and ambushes on carabinieri and other security forces , with the 1967 attack on a patrol at Cima Vallona being the most notorious
