A Norwegian-Iranian dual citizen has been arrested in Iran, Norway's foreign ministry told AFP on Monday.
"The Ministry of Foreign Affairs is aware that a Norwegian citizen has been arrested in Iran, but due to our obligation to respect confidentiality we cannot provide further details," ministry spokesman Mathias Rongved said in an email.
He confirmed the individual was a dual Norwegian-Iranian national and noted the government advises against travel to Iran.
On its website, the Norwegian government states that Iran does not recognise dual citizenship, and it is "therefore very difficult -- virtually impossible -- for the embassy to assist Norwegian-Iranian citizens if they are imprisoned in Iran".
The US-based Human Rights Activists News Agency (HRANA) identified the dual national as Shahin Mahmoudi, born in 1979.
It said she was arrested on December 14 after being ordered to report to authorities in Saqqez, in Iran's western Kurdistan province.
She is being held at a detention center in Sanandaj, it added.
HRANA said her family had not been informed of the reason for her arrest nor had they received any news of her health and well-being.
