Oscar Pistorius, who has been charged with murdering his girlfriend, has been granted permission to travel abroad by a South African judge.

"The applicant is entitled to use his passport to travel outside the Republic of South Africa," Judge Bert Bam said.

The 26-year-old Olympic and Paralympic track star, a double amputee since infancy, also no longer needs to report to a probation officer.

The decision eased initially very strict bail conditions.

Mr Pistorius is charged with the Valentine's Day murder of 29-year-old Reeva Steenkamp.

Prosecutors said Mr Pistorius committed premeditated murder when he fired four shots into a locked toilet door, hitting Ms Steenkamp on the other side.

She suffered gunshot wounds to her head, hip and arm.

Mr Pistorius has said the killing was a tragic mistake and that he had mistaken Ms Steenkamp for an intruder and opened fire in a blind panic.

Mr Pistorius' lawyers said that he had no immediate plans to compete, but might eventually need to run at track meets again to earn money.
