Rights groups join Caster Semenya's battle

South African rights groups have vowed to petition the United Nations and African Union over the latest ruling that the country's Olympic 800-metre champion Caster Semenya cannot compete unless she takes hormone-suppressing drugs.

Switzerland's Supreme Court last week dismissed Semenya's appeal against a decision by the Court of Arbitration for Sport on eligibility criteria for athletes with differences of sexual development (DSD).
