Iranian authorities detained two British nationals in the southern city of Kerman on unspecified security charges, Iran’s official news agency IRNA reported Wednesday.
The family of the two, in a Saturday statement released by the British Foreign Office, named them as Craig and Lindsay Foreman.
The couple, in their early 50s, had been on a motorbike trip across the world and had only planned on being in Iran for five days.
British media reports indicate that the couple were heading for Australia, having crossed into Iran from Armenia on December 30, according to social media posts.
Lindsay Foreman was carrying out a research project as part of the journey, asking people what constitutes a good life.
The Foreman family acknowledged their detentions and emphasized the distress caused by the incident.
"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," the family said.
