Austrian authorities say they have arrested eight people on suspicion of belonging to a terrorist organisation through possible connections to the Islamic State group. A statement from the public prosecutor in the city of Graz said the suspects were arrested on Thursday after raids on several residences in Graz and Vienna. Watch What Else is Making News The statement said the eight are suspected of "participation in a terrorist organisation (IS)." It said 800 police officers were involved in the operation. The raids come less than a week after police in Vienna detained a 17-year-old they describe as belonging to "radical Salafist" circles who they said has confessed to experimenting with building a bomb. But the statement said the raids had been planned for "a longer time," suggesting no immediate link.
