South Africa is gearing up for the trial of Oscar Pistorius, which starts on 3 March.

Prosecutors say 27-year-old Pistorius killed his girlfriend Reeva Steenkamp in the early hours of Valentine's Day after an argument. He says he shot Steenkamp by mistake in the belief that she was an intruder.

Pistorius was the first double-amputee to run at the world championships and the Olympics. He faces a possible life sentence with a minimum of 25 years in prison if he is convicted of premeditated murder.
