The Guardian:

The British Foreign Office has updated its travel advice on Iran, warning its citizens, especially those with dual Iranian nationality, of a risk of being arbitrarily detained.

The British government relaxed its advice against all but essential travel to Iran in July 2015 after the landmark nuclear agreement. But a stalemate over the fate of at least two British-Iranians currently detained in Tehran appears to have led the FCO to amend its instructions, although it has not raised concerns to the same level as before the nuclear deal.

“British nationals – including dual British/Iranian nationals – face greater risks than nationals of many other countries,” reads the new advice, which was updated on Friday. “The security forces may be suspicious of people with British connections. The risks are likely to be higher for independent travellers or students than for people travelling as part of an organised tour or business people invited by the Iranian authorities or companies.”

The warning will be bad news for Iran as it struggles to strengthen economic ties with the UK and attract more foreign tourists. The ongoing detentions of Nazanin Zaghari-Ratcliffe, a British-Iranian woman held since April, and 76-year-old businessman Kamal Foroughi, a dual national in prison since May 2011, have undermined efforts by London and Tehran to improve relations.
