Oscar Pistorius sentencing for Reeva Steenkamp begins

South African athlete Oscar Pistorius is a "broken" man, a defence witness has said at his sentencing hearing.

He was convicted of murder at the end of last year for the 2013 murder of his girlfriend Reeva Steenkamp.

He faces a jail term of 15 years, but his sentence can be reduced due to time already spent in prison and mitigating factors.
