Oscar Pistorius did not have a mental disorder when he killed his girlfriend, a psychological report said as his murder trial resumed.

This means the Olympic athlete was criminally responsible for his actions when he shot her, the prosecution said.

The defence team argued Mr Pistorius was suffering from an anxiety disorder.

The athlete denies deliberately killing Reeva Steenkamp. He says he shot her accidentally in a state of panic after mistaking her for an intruder.

Both prosecution and defence have accepted the results of the report.

The court heard from Dr Gerry Versfeld, who amputated Mr Pistorius' legs when he was just 11 months old. He was born without the fibulas in both of his legs but went on to become an Olympic athlete.

Dr Versfeld testified about the impact of the disability on Mr Pistorius, 27, and to what extent he can walk without his prosthetic legs.

The defence is expected to finish presenting its evidence in the next few days.

Ms Steenkamp, a 29-year-old model and law graduate, was shot through a toilet door at Mr Pistorius' house in Pretoria on Valentine's Day last year.

The couple had been dating for three months.
