The parents of Reeva Steenkamp have accused six-time Paralympic champion Oscar Pistorius of killing their daughter deliberately.

The 28-year-old has served 10 months behind bars in South Africa after being handed a five-year sentence for killing his girlfriend.

Steenkamp was shot dead through a toilet door at Pistorius's home in Pretoria in the early hours of Valentine's Day in 2013.

Pistorius, who testified in court that he mistook his girlfriend for an intruder when he fired the shots, escaped a murder conviction, but was found guilty of culpable homicide (manslaughter).

During an interview with Australia's Channel Seven, Reeva's father Barry Steenkamp said: "What actually came out in court is not the truth. He got angry, she went off to the toilet, locked herself inside, and then him pulling out the gun and shooting."

Reeva's mother June added: "Why didn't he just let her walk away?"

Last week, Pistorius was denied early release from prison.
