South African prosecutor starts Pistorius cross-examination

South African state prosecutors started cross-examining Olympic and Paralympic sprinter Oscar Pistorius on Wednesday, vowing to "get to the truth" surrounding the killing of Pistorius' girlfriend on Valentine's day last year.

"You killed Reeva Steenkamp, didn't you?" prosecutor Gerrie Nel asked bluntly at the start of questioning, to which Pistorius, who is accused of murder, responded that he had made a mistake.
