OSCAR Pistorius has vomited in the dock at his murder trial as he heard graphic details of the injuries sustained by the girlfriend he fatally shot.

The testimony of ­Professor Gert Saayman, the pathologist who performed the autopsy on Reeva Steenkamp's body, was not broadcast because of its explicit content under an order from Judge Thokozile Masipa but journalists were allowed to report the evidence without directly quoting the witness.

The double-amputee runner, hunched over on a bench, reacted to the description of Ms Steenkamp's wounds by vomiting and retching repeatedly, prompting Judge Masipa to briefly halt the evidence to ask chief defence lawyer Barry Roux to attend to his client.

Mr Saayman described bullet wounds to Ms Steenkamp's body, one to the right side of the head, one to the right arm and one to the right hip area.

He also described exit wounds caused by the bullets and other abrasions and discolouration of the skin, consistent with the impact of a bullet fired through a wooden object such as a door.

Pistorius, the first ­amputee to run in the Olympics, is charged with the premeditated murder of Ms Steenkamp, 29, who he admits shooting. Pistorius, 27, says he thought his girlfriend was a dangerous intruder. The trial continues.
