European prisoners freed by Iran.

Iran has released two Austrian-Iranian citizens and a Danish man from prison, with the help of Oman and Belgium. The Austrian and Danish foreign ministers expressed relief and gratitude for their release. The reasons for their imprisonment were not specified, and it is unclear what Iran obtained in return for the releases. The releases come after Oman's Sultan Haitham bin Tariq visited Iran, and the prisoners had been held for several years.
