Good morning and welcome to live updates from the Oscar Pistorius trial, due to start at 8:00 GMT (10:00 local time) in Pretoria, South Africa.
The 27-year-old athlete, who competed at both the London 2012 Paralympic Games and the Olympics, is charged with murdering his girlfriend Reeva Steenkamp - a charge he vigorously denies.

International interest in the case is high. The BBC's Karin Giannone is among the media crowd outside the court.
Three weeks has been allocated for this trial, but it could well take longer, say legal analysts.
Audio of the entire trial will be broadcast, but some testimonies from witnesses will be excluded from the TV coverage. Mr Pistorius' legal team had unsuccessfully argued against both TV and audio broadcast, and it is expected that his witnesses will exercise their right not to be shown on TV.
There are 80 journalists who have been granted access to the courtroom - 40 South African reporters, and 40 journalists from the foreign media. A further 200 journalists have access to an "overspill" room outside of the courtroom, legal analysts say.
