Oscar Pistorius trial - 3 July- in 60 seconds

South African double amputee Oscar Pistorius has been greatly affected by his disability, a sports doctor has told his murder trial.

Wayne Derman told the court in Pretoria that the Paralympian 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.

The prosecution argues that he killed her deliberately after a row.
