South African Olympic and Paralympic star Oscar Pistorius has strongly rejected a charge that he murdered his girlfriend, Reeva Steenkamp.
Ms Steenkamp, a 29-year-old model, was shot dead at Mr Pistorius's home near Pretoria on Thursday.
Appearing in court in Pretoria, Mr Pistorius wept as prosecutors vowed to pursue a charge of premeditated murder.
An application for bail was postponed until next Tuesday and the athlete will remain in police custody.
Dubbed "blade runner", he made history last summer by becoming the first double-amputee track athlete to run in an Olympic Games.
"The alleged murder is disputed in the strongest terms", said a statement released by Mr Pistorius's family and management company "Our thoughts and prayers today should be for Reeva and her family - regardless of the circumstances of this terrible, terrible tragedy," it said.
They were the first words released on behalf of the 26-year-old athlete since Ms Steenkamp was found fatally wounded at his home in the gated Silver Lakes development outside the South African capital.
'Traumatised'
However, he was seen hours earlier, sobbing during his appearance at Pretoria Magistrates Court.
Dozens of reporters witnessed the hearing, where chief magistrate Desmond Nair was presiding.
The BBC's Andrew Harding, who was there, said the defendant cut a lonely figure, holding his head forward and breathing heavily through tears.
Prosecutor Gerrie Nel argued for a "premeditated murder" charge. Mr Pistorius slumped forward at the mention of the words.Media access was discussed at the 40-minute session and the magistrate ruled that there should be no live recording of the bail hearings.
Mr Pistorius's team had argued against such coverage and cited his "extremely traumatised state of mind".
Both prosecution and defence agreed Mr Pistorius could remain in custody at a police station and not in prison.
Members of Mr Pistorius's family, including sister Aimee, brother Carl and father Henke, were in the courtroom.
Relatives reached forward to touch Mr Pistorius's shoulder as he stood and left the courtroom at the end of proceedings.
Mr Pistorius had earlier arrived at court in the back of a police vehicle, hiding his face with a jacket and notebook.
Forensic scientists are expected to continue examining the house in the Silver Lakes area on the outskirts of South Africa's administrative capital where Ms Steenkamp, 29, died.
Correspondents say the athlete's arrest has stunned the country where he is considered a national hero.
He is known as "blade runner" because of the carbon fibre prosthetic blades he races in. He was born without a fibula in both legs and had his legs amputated below the knee before his first birthday.
Police were called to his home in the early hours of Thursday morning.
They found paramedics treating a 29-year-old woman with four gunshot wounds to the head and upper body. She died at the scene, and officers recovered a 9mm pistol.
A post-mortem examination is being carried out on Friday but the results will not be made public, police said.
Mr Pistorius and Ms Steenkamp had reportedly been dating since November.
Mr Pistorius dominated in his category at successive Paralympic Games, but in 2008 he won a legal battle over his blades - which critics said gave him an unfair advantage - with the International Association of Athletics Federations (IAAF) for the right to compete in able-bodied competitions.
He reached the 400m semi-finals in the London 2012 Olympics. At the Paralympics he won silver in the T44 200m, gold in the 4x100 relay and gold in the T44 400m, setting a Paralympic record.
South Africa has one of the highest rates of crime in the world and many residents keep weapons to protect themselves against intruders.
But gun ownership is strictly regulated and it is not easy to obtain a licence.after the court hearing.
