The husband of a British-Iranian woman held in Iran on suspicion of being a spy while traveling with her young daughter says she has been sentenced to five years in prison.

Richard Ratcliffe said his wife, Nazanin Zaghari-Ratcliffe, was sentenced on "secret charges" by a Revolutionary Court. He says he learned of his wife's sentence when she called him from prison.

There was no word on her sentence in Iranian state media. Iranian officials could not be reached for comment on Friday, the start of the Eid al-Adha holiday.

Zaghari-Ratcliffe works for the Thomson Reuters Foundation, the news agency's charitable arm.

Zaghari-Ratcliffe was detained in April while trying to fly out of the country with her toddler daughter, Gabriella, who remains in Iran with family after authorities seized her passport.
