Caster Semenya being 'targeted' by IAAF, says Bryan Habana

South African rugby star Bryan Habana asks if Caster Semenya is being specifically targeted by the governing body of athletics, the IAAF.

The South African middle-distance runner is appealing against a ruling which restricts testosterone levels in female runners.

This week, IAAF president Lord Coe said the new regulations are "to protect the sanctity of fair and open competition."
