VIENNA -- Austrian police on Friday arrested three 15-year-old schoolboys suspected of planning to murder their headmaster and three teachers. The teenagers are accused of instructing a classmate to acquire handguns for them to shoot staff at their school in Neunkirchen, some 60 km (40 miles) south of Vienna, police in the state of Lower Austria said, according to Reuters. The teachers and headmaster had previously reported the boys to the police for smearing swastikas around the school and greeting each other with Nazi salutes.
