Oscar Pistorius trial: Neighbour 'heard screams'
A neighbour of South African athlete Oscar Pistorius has told a court in Pretoria that she was awoken by a woman's "terrible screams" in the early hours of 14 February 2013.
Mr Pistorius has pleaded not guilty at the start of his trial for the murder of his girlfriend Reeva Steenkamp.
He shot dead the 29-year-old model and reality TV star at his home, saying he mistook her for an intruder.
The neighbour, Michelle Burger, said cries for help were followed by shots.
At the scene
Oscar Pistorius seemed much more composed at the start of his televised murder trial - unlike the man who broke down on the stand during his bail hearing last year.
After pleading not guilty, he looked on as his neighbour Michelle Burger gave evidence, describing how that she heard "blood curdling screams" in the early hours of the morning when Reeva Steenkamp died. Dressed in a charcoal suit and a white shirt, he sat quietly writing on his notepad.
There is massive interest in the case here - it is possibly the most publicised case since Jacob Zuma was cleared of rape in 2006, three years before he became president. And it does not take much for a matter to become political here. Outside court, members of the local African National Congress Women's League, sang struggle songs, telling me: "We are here for Reeva; she was killed and we want answers."
"She screamed terribly and she yelled for help. Then I also heard a man screaming for help. Three times he yelled for help," Ms Burger told the high court in the capital.
She said she called security and then heard four gunshots.
The arrest of the national sporting hero astounded South Africa.
The 27-year-old double amputee won gold at the London 2012 Paralympic Games and also competed at the Olympics.'Traumatic'
For the first time in South Africa, parts of the trial are being televised live, although Ms Burger's testimony, in Afrikaans, was only relayed in audio.
The start to proceedings at the court in the capital on Monday was delayed by 90 minutes as a Afrikaans translator was absent. It has now adjourned for the day.
The BBC's Andrew Harding in the courtroom said Mr Pistorius looked calm, or at least neutral as he arrived in court - a far cry from the emotional wreck he seemed at the bail hearing last year.
Mr Pistorius's uncle, brother and sister were also in court; next to them on the relatives' bench sat the family of Ms Steenkamp, including her mother June, our correspondent said.
Mr Pistorius pleaded not guilty to all charges, including the "wilful and intentional murder of Reeva Steenkamp" as the trial began.
His lawyer read out a statement from the athlete, giving his version of events of how Ms Steenkamp died, saying he believed his girlfriend was in bed when he shot at the toilet door in the early hours of Valentine's Day last year.
Ms Burger told the court she lived nearby on a neighbouring gated estate to Mr Pistorius in Pretoria - and she and her husband were sleeping with the windows open.
"It was very traumatic for me. You could hear blood curdling screams," she said.

Following a lunch break, the defence lawyer Barry Roux began questioning Ms Burger over differences between her sworn statement and her testimony.
State prosecutors say Mr Pistorius planned the killing and shot Ms Steenkamp after a row.
If found guilty of premeditated murder, he could face life imprisonment.
He has also been charged with illegally possessing ammunition.
There are no juries at trials in South Africa, and his fate will ultimately be decided by Judge Thokozile Masipa.
Much of the case will depend on ballistic evidence from the scene of the shooting, correspondents say.
On the anniversary of the shooting, Mr Pistorius released a rare statement in which he said: "The loss of Reeva and the complete trauma of that day, I will carry with me for the rest of my life."
