Oscar Pistorius trial: Paralympian has 'high anxiety'

Oscar Pistorius has been greatly affected by his disability, a sports doctor has told his murder trial in Pretoria.

Defence witness Wayne Derman told the court that the double amputee suffered "significant stress and anxiety".

Mr Pistorius says he shot his girlfriend Reeva Steenkamp after mistaking her for an intruder in their house last year.
