Oscar Pistorius reportedly vomited and retched in court today on day six of his murder trial at the High Court in Pretoria as a pathologist took to the stand to given further detail of the injuries sustained by Reeva Steenkamp.

Mr Pistorius - a highly-successful Paralympic athlete - is accused of the pre-meditated murder of Ms Steenkamp at his home in February 2013 - something he denies.

He was visibly finding it difficult to cope with Professor Gert Saayman's testimony on Monday afternoon as a bucket was placed alongside him.

Certain rules imposed mean media reporting of Saayman's descriptions of the victim's wounds is very limited, however.

Earlier on day six of the trial, security guard Pieter Baba - who first appeared as a witness on Friday - re-took the stand was was cross-examined by Mr Pistorius' defence lawyer, Barry Roux.

The main bone of contention with his testimony appeared to be the claim that Baba was the one who telephoned Pistorius after neighbours had reported hearing gunshots on that fateful evening and with Baba's assertion that Mr Pistorius had initially told him "Everything is fine," before ringing him back later in tears.

Roux, though, seemed to suggest that was in fact Mr Pistorius who first made the call and told the security guard "I am fine".

Such a version of events was rejected by Mr Baba, who insisted to the court that his testimony was the truth.

If Pistorius is eventually found guilty of the charges against him, he could face life imprisonment. South Africa does not have a jury system, so the decision will rest with Judge Masipa

The trial continues.
