South Korea has denied entry to the leader of a religious sect that claimed it had produced the first cloned human.
The founder of the Raelian movement, Claude Vorilhon, was forced to leave the country after being detained for nine hours at Incheon airport in Seoul.
The Justice Ministry said it was concerned that he might engage in cloning activities.
Clonaid, the sect's cloning company which Mr Vorilhon set up, has been investigated over reports that South Korean women have been involved in its cloning experiments.
The sect said Seoul's rejection of their leader was discrimination against religious minorities.
