Why does Austria stay silent over dual national’s arrest six years ago in Iran?

Iranian-Austrian Kamran Ghaderi is serving a 10-year sentence for spying and his family are still waiting for answers

Six years ago on New Year's Day, an Iranian-Austrian IT businessman said goodbye to his wife and three children and boarded a flight from Vienna to Tehran via Istanbul. Kamran Ghaderi was due to return five to six days later, but instead, on 2 January 2016, he was arrested and has now spent six years in Evin prison in Tehran.

In October 2016, he was sentenced to 10 years for spying for a foreign country at a trial in which neither he nor his lawyer were able to say more than two words. His sentencing was based on a confession he gave under what his wife, Harika, says was torture, in the belief she might be in danger. No written judgment has ever been given to his family.
