Olympic athlete Oscar Pistorius has been found guilty of murder after a South African appeals court overturned an earlier manslaughter verdict.
He killed his girlfriend Reeva Steenkamp in February 2013 after shooting her four times through a locked toilet door.
He is currently under house arrest after spending one year of his original five-year sentence in jail.
Pistorius will have to return to court to be re-sentenced, for murder.

South Africa’s Supreme Court of Appeal ruled that the lower court did not correctly apply the rule of dolus eventualis.
Pistorius always maintained that he believed there was an intruder in the house but the judge said that the identity of the person behind the door was “irrelevant to his guilt”.
The double amputee was released from prison on 19 October. Under South African law, he was eligible for release under “correctional supervision”, having served a sixth of his sentence.
Pistorius can challenge the ruling in the constitutional court but only if his lawyers can argue that his constitutional rights have been violated.
