Oscar Pistorius was convicted of murder on Thursday by South Africa's Supreme Court of Appeal, which threw out his earlier conviction on a lesser charge for shooting dead his girlfriend in 2013.

Pistorius is now set to go back to jail after he was released on parole in October having served one year of his five-year sentence for culpable homicide - the equivalent of manslaughter.

"Guilty of murder, with the accused having criminal intent," judge Eric Leach told the court in a dramatic legal reversal.
