The sentencing of Oscar Pistorius is underway at the North Gauteng High Court in Pretoria, with the athlete facing a potential sentence of up to 15 years in jail.

Pistorius was convicted of culpable homicide last month after he shot his girlfriend Reeva Steenkamp on Valentine’s Day in 2013.

The court is expected to hear from three witnesses for the defence, as well as an official witness from South Africa’s Department of Correctional Services.

The prosecution is likely to put forward at least two witnesses, with the whole process expected to finish before the end of the week.

Judge Thokozile Masipa cleared Pistorius of murder last month but convicted him of the lesser charge of culpable homicide and also found him guilty of one charge of negligently discharging a firearm in a crowded restaurant in Johannesburg in January 2013.
