On the South Korean island of Jeju, a tourist hot spot famed for blue waters and sandy beaches, Lee Hyang is angry.

The target of her wrath? More than 500 asylum-seekers from war-torn Yemen looking for a safe place to live and work.

Lee, who leads a local group demanding the Yemenis be deported, believes outsiders compete for jobs and pose a threat to local safety. The refugees she saw at the immigration center looked "really scary," she said.
