A man has died after he and a friend were shot seven or eight times as they sat in a car in western Sydney.
The pair, both aged in their early twenties, were shot seven or eight times as they sat in a car near the western end of Greenacre Road, Greenacre, at about 1.20pm (AEDT) on Sunday.
One of the men, who was sitting in the front passenger seat of the vehicle, died at the scene, having been shot multiple times in the chest and shoulder.
The other, who was the wheel of the car, was rushed to hospital in a critical condition after being shot in the chest.
One witness said the men were in a grey Holden Commodore and were shot at by a gunman travelling in another car.
'The passenger died straight away, I think they (the bullets) were meant for the passenger,' Greenacre resident George Mourade, 44, said.
'He was trying to open the door and run away but he died face down.
'The driver was battling to survive ... I don't know if he'll make it.'
Mr Mourade, who described Greenacre as a 'beautiful area', said he was among the first on the scene after hearing seven or eight bullets being fired.
He said he didn't see the gunman, but added: 'Somebody drove away, they'd shot at them.'
Mr Mourade said he wasn't sure who the victims were but suggested they might have lived locally.
The dead man's body remains at the scene, covered in a white sheet on a grass reserve outside a house in Greenacre Road, not far from Greenacre Park Reserve.
Police are at the scene gathering evidence.
There have been dozens of shootings in western Sydney since January, with many said to involve gangs fighting over drugs and territory.
