Two Australian citizens detained in Iran have been identified as Jolie King and Mark Firkin.Ms King, who also holds a UK passport, and Mr Firkin were blogging their travels in Asia and the Middle East.
They were reportedly arrested 10 weeks ago near Tehran but news of the arrest, and that of another British-Australian woman, came to light on Wednesday, reports BBC.
Several dual nationals have been detained in Iran in recent years, including the British-Iranian woman Nazanin Zaghari-Ratcliffe.
Ms King - who has dual UK and Australian nationality - and Mr Firkin, an Australian citizen, were reported to have been travelling on Australian passports.
In 2017, the couple left Western Australia to embark on a major trip driving across Asia to the UK. They were documenting their adventures on Instagram and Youtube, where they had more than 20,000 followers.
Videos of their travel through a dozen countries featured their cultural interactions and often showed drone footage of the natural landscape."Our biggest motivation... is to hopefully inspire anyone wanting to travel, and also try to break the stigma around travelling to countries which get a bad wrap [sic] in the media," the pair wrote online.
Few details of the circumstances of their arrest have been made public, but the Australian Broadcasting Corporation said they had reportedly been flying a drone without a permit.
They are believed to be being held in Tehran's Evin prison.
The second detained British-Australian woman is reported to be a University of Cambridge-educated scholar who was lecturing at an Australian university.
She has reportedly already been tried on unknown charges and jailed for 10 years.
The two British-Australian women are believed to be the first British passport holders without dual Iranian nationality to be held in the country in recent years.
