A 13-year-old lesbian has become the latest victim of 'corrective rape' in South Africa, prompting activists to call for direct retaliatory action. The girl, who is said to be open about her sexuality, was raped in Pretoria, a government spokesman said. Campaigners say so-called corrective rape, in which men rape lesbians to 'cure' them of their sexual orientation, is on the increase in South Africa. Last month, a 24-year-old woman who belonged to a gay and lesbian rights group was stoned to death after an apparent gang rape.
