Pistorius trial day 21 - in 60 seconds

The prosecutor at the Oscar Pistorius murder trial has suggested the South African athlete is using his emotions "as an escape".

He broke down in tears four times on Monday and has also vomited in court.

"Now you trying to be emotional and it's not working," said prosecutor Gerrie Nel.

Mr Pistorius admits killing girlfriend Reeva Steenkamp in February last year, but says he fired his gun after mistaking her for an intruder.
