Imane Khelif, the boxer at the center of the Olympic gender controversy, is skipping a boxing tournament in the Netherlands after World Boxing announced mandatory sex testing for all athletes.

World Boxing has apologized after Imane Khelif was named in their announcement on mandatory sex testing for all boxers in their competitions, saying the Paris Olympics gold medalist’s privacy should have been protected.

Khelif, a biological female who faced transphobic attacks regarding her physical appearance and gender during last summer's Paris Olympics, was singled out in the organization's announcement.
