Nazanin Zaghari-Ratcliffe's husband recalls 'terrifying' detention

Nazanin Zaghari-Ratcliffe - a charity worker with dual British and Iranian citizenship - was detained while trying to leave Iran with her baby daughter after visiting relatives in April 2016.

A court in Iran has rejected an appeal against a five-year prison sentence handed to her in September for security offences.

Her family denies she broke any laws.

Her husband, Richard Ratcliffe, who is from London, says the detention of his wife, 38, is a "stain" on Iran.
