South African prosecutors have started an appeal hearing on whether athlete Oscar Pistorius should be convicted of murder instead of culpable homicide.

According to BBC news the Paralympian was released from prison last month after serving one year of his five-year term for killing his girlfriend Reeva Steenkamp.

Pistorius, 28, shot her through a locked bathroom door in 2013 but insists he thought she was an intruder.

He could be sent back to jail if appeal judges overturn the original verdict.

Pistorius is currently under house arrest, and is not attending the hearing at South Africa's Supreme Court of Appeal in Bloemfontein.he Paralympian was released from prison last month after serving one year of his five-year term for killing his girlfriend Reeva Steenkamp.
