World Boxing will introduce mandatory sex testing for all boxers in its competitions, the body said on Friday, adding that Paris Olympics gold medallist Imane Khelif will not be allowed to compete until she undergoes such a test.

Imane Khelif, whose gold medal at last year’s Paris Olympics caused a global scandal, has been banned from competing in all future World Boxing events in the women’s category unless the Algerian can provide proof of being biologically female.
