Oscar Pistorius has started giving evidence in his murder trial and has apologised to Reeva Steenkamp's parents.
The athlete, who denies murder, says the shooting of his girlfriend has left him terrified and plagued by nightmares.
He told the court that he believed he was keeping her safe from an intruder.
Here's the moment when the athlete took the stand.
He says when she went to bed on the evening of Valentine's Day "she felt loved".
This is what he said to Reeva's mum and dad.
