Intro:

Oscar Pistorius was accused by a prosecutor on Friday of shooting his girlfriend through a toilet door as the couple talked and argued in the early hours of Valentine's Day last year.

A dramatic courtroom exchange ended Oscar Pistorius's first week testifying at his murder trial.

Prosecutor Gerrie Nel pushed the Paralympian on his version of the exact events in the seconds before he killed Reeva Steenkamp by firing four times through the stall door in his bathroom with his 9 mm pistol on February 14, 2013.

Pistorius says he shouted at what he thought was an intruder in his house and also at Steenkamp to call the police.

The double-amputee Olympian is charged with premeditated murder for Steenkamp's shooting death.

He claims he shot the model and rising reality TV star by mistake, thinking she was an intruder about to come out the toilet and attack him.

SOUNDBITE: (English) Gerrie Nel, Prosecutor: ++BEGINS ON MID OF GALLERY++

"Of your whole version Mr Pistorius this is the most improbable. Reeva at that stage is three meters away from you, in a toilet."

UPSOUND: (English) Oscar Pistorius: ++NOT IN VISION++

"I didn't know that my lady, I thought she was in the bedroom."

SOUNDBITE: (English) Gerrie Nel, Prosecutor:

"No, no. In fact. I am talking about the facts. At that stage when you shouted and screamed at Reeva to phone the police she is three metres away from you in a toilet."

UPSOUND: (English) Oscar Pistorius: ++NOT IN VISION++

"That's correct my lady"

SOUNDBITE: (English) Gerrie Nel, Prosecutor:

"And she never uttered a word."

UPSOUND: (English) Oscar Pistorius: ++NOT IN VISION++

"That's correct my lady"

SOUNDBITE: (English) Gerrie Nel, Prosecutor:

"It's not probable. She would be scared, she would shout out and talk to you. You are in the same room."

4. 00:43 SOUNDBITE: (English) Gerrie Nel, Prosecutor:

"On your version and the state's version she is standing behind the door facing the bathroom. Facing you that's shouting."

UPSOUND: (English) Oscar Pistorius: ++NOT IN VISION++

"That's correct my lady."

5. 00:58 SOUNDBITE: (English) Gerrie Nel, Prosecutor: ++BEGINS ON MID OF JUDGE++

"Now if she was scared she would have not have been there. She would have hid somewhere in the toilet."

UPSOUND: (English) Oscar Pistorius: ++NOT IN VISION++

"I can't say what she would have done, I don't think anybody can say what she would have done."

SOUNDBITE: (English) Gerrie Nel, Prosecutor:

"I can. Mr. Pistorius I think the state can. She was talking to you. She was standing right in front of the toilet door talking to you when you shot her."

UPSOUND: (English) Oscar Pistorius: ++NOT IN VISION++

"It's not true my lady."

SOUNDBITE: (English) Gerrie Nel, Prosecutor:

"That's the only reasonable explanation for her for standing upright. That's the only reasonable explanation why you shot in the hip."
