Oscar Pistorius quizzed over Reeva Steenkamp killing

South Africa's Oscar Pistorius has faced hostile questioning about his version of events on the night he shot his girlfriend Reeva Steenkamp.
Prosecutor Gerrie Nel began his cross examination by pushing Mr Pistorius to acknowledge the full magnitude of his actions on 14 February 2013.
The athlete said he made a "mistake" when he shot Ms Steenkamp in his home.
"You killed a person, that's what you did! You shot and killed her, won't you take responsibility?" Mr Nel said.
A graphic picture of Ms Steenkamp's head was shown to the court for the first time, prompting anguish from Mr Pistorius and a further adjournment of proceedings, according to a news agency.
