A major search operation has been launched in Greece after a British scientist failed to return from a morning run.
The woman, named locally as Natalie Christopher, went missing on Monday hours before she and her partner were set to return from the island of Ikaria.
Police, firefighters, the coast guard and volunteers are participating in the search for the 35-year-old.
She is believed to be an astrophysicist who lives in Cyprus, and had been on the Aegean island since the beginning of the month.
Ms Christopher’s running group, Cyprus Trail Runners, launched a crowdfunding campaign which raised more than 3,000 euros within a few hours.
The group are sending two of their members to Ikaria to help join the search.
A helicopter is also participating in the search. Police said they were keeping all lines of inquiry open.
Greek police spokesperson Theodoros Chronopoulos told state broadcaster Cybc: “From what we were told, the couple spoke on the phone at approximately 10am, and she told him that she went for a run in the area.”
Her disappearance follows the death of another woman on nearby Crete last month.
American scientist Suzanne Eaton went missing after also going for a run on July 2.
But she was found dead inside a World War Two bunker after reportedly being suffocated.
Ms Eaton was a molecular biologist at the world-renowned Max Planck Institute in Dresden, Germany and had been attending a conference in the town of Chania.
