The family of Britons Craig and Lindsay Foreman, who have been detained in Iran, said the situation was causing “significant concern”.
They were reportedly detained in January but Iran’s state-run media revealed this week they had been accused of security-related offences.
The couple were reportedly traveling around the world on motorbikes when they were held.
A statement from the family said: “We would like to take this opportunity to address the distressing situation concerning Craig and Lindsay Foreman who are currently being detained in Kerman, Iran.
“This unexpected turn of events has caused significant concern for our entire family, and we are deeply focused on ensuring their safety and well-being during this trying time.
“We are actively engaging with the British government and relevant authorities, working diligently to navigate the complexities of this matter.
“The family are united in our determination to secure their safe return.”
