Oscar Pistorius' older brother Carl remains in an intensive care unit in a South African hospital and is on a ventilator after a serious car crash last week.

The Pistorius family said in a statement Wednesday that Carl Pistorius was still in ICU at the hospital in the South African capital Pretoria "due to the serious nature of the injuries sustained in the accident." The family said he was "showing signs of improvement." They didn't give details of his injuries.

Carl reportedly sustained multiple fractures in a head-on collision on a highway in northern South Africa on Friday.

Oscar Pistorius is due to return to a Pretoria courthouse on Thursday for the start of final arguments in his murder trial for shooting to death his girlfriend last year.
