DUBAI, United Arab Emirates — Iran has sentenced an Iranian-American art dealer and his wife to prison for being Zoroastrians, a New York-based human rights group said Wednesday. It is the latest case in which Tehran has imprisoned people of Iranian descent who hold dual citizenship.

The art dealer, Karan Vafadari, was sentenced to 27 years in prison, while his Iranian wife, Afarin Neyssar, who has permanent residency status in the United States, received a 16-year sentence, said the group, the Center for Human Rights in Iran.

The sentences have yet to be reported in Iran. Iran’s mission to the United Nations did not immediately respond to a request for comment.

The two were arrested by Iran’s paramilitary Islamic Revolutionary Guards Corps in July 2016. Little information has come out about their case since then.
