Hundreds of South Africans have lined the streets in the South African city of Pretoria to catch a glimpse of 800-meter gold medalist, Caster Semenya, as she and other members of the athletics team toured in an open top bus.

Also on Tuesday, Semenya was welcomed by South African President Jacob Zuma, who greeted her and fellow athletes at the presidential guest house. Zuma expressed his support to Semenya, who has been the subject of questions about her gender.

Earlier, the president of Athletics South Africa said he had resigned from his seat on the International Amateur Athletics Federation board in protest at the organization's treatment of Semenya.

Her victory in Berlin came after world athletics officials said they were conducting gender tests after questions arose about her muscular build and deep voice.
