SOUTH AFRICA: Oscar Pistorius' agent has cancelled all future races the athlete was contracted to take part in.

Peet van Zyl said Pistorius' "key focus" is now defending himself against the charge of murdering girlfriend Reeva Steenkamp.

Mr van Zyl added there is "no option" but to cancel Pistorius' track dates indefinitely "to allow Oscar to concentrate on the upcoming legal proceedings".

The double amputee is being held at a police station in Pretoria.
