Kermani said she flew out of Tehran on Monday but had been free in recent months as she appealed a travel ban.
After holding Amiri for months, Iran in 2019 sentenced the British Council worker to 10 years in prison on charges of spying on cultural activities in Iran. Her arrest highlighted the dangers faced by those with Western ties in Iran after former President Donald Trump abandoned Iran's landmark nuclear deal with world powers and piled crushing sanctions on the country.
A number of dual nationals have landed in Iranian prisons in recent years as tensions between Tehran and the West simmer. Rights groups accuse Iran of holding dual nationals as bargaining chips for money or influence in negotiations with the West, something Tehran denies.
For over five years a British-Iranian worker for the Thomson Reuters Foundation, Nazanin Zaghari-Ratcliffe, has been detained in Iran on internationally refuted spying charges.
After completing her sentence, Zaghari-Ratcliffe walked free from prison last year — only for authorities to sentence her to another year in jail on new propaganda charges. Zaghari-Ratcliffe's family links her imprisonment to a long-running $530 million debt dispute owed to Tehran by London for Chieftain tanks that were never delivered.
Another British-Iranian dual national, Anoush Ashoori, was sentenced to 12 years in prison at the same time as Amiri and remains in detention. A U.N. panel has lambasted what it calls “an emerging pattern involving the arbitrary deprivation of liberty of dual nationals” in Iran.
Meanwhile, Western negotiators have raised alarm that time is running out to resuscitate Iran’s collapsed nuclear deal.
After a five-month hiatus in the talks, Iran under recently elected hard-line President Ebrahim Raisi has presented maximalist demands at the negotiating table even as it accelerates its nuclear program. Iran now enriches uranium over 60% — a short step from weapon’s grade levels — and spins far more advanced centrifuges and more of them than were ever allowed under the accord.
