Two men were shot dead and another man was wounded by gunfire in separate incidents in the past week, with police still hunting those responsible.

On Monday night, two men were standing in car park outside an Eastlakes apartment building in Sydney's south-east when a number of bullets were fired from a passing vehicle.

One man was fatally shot in the torso, while another sustained an injury to his calf.

The incident is believed to have been part of an ongoing turf war between the Hells Angels and Comanchero outlaw motor cycle gangs.

In a second shooting on Friday, a man aged in his late 40s was gunned down outside a home in Abbotsbury in Sydney's south-west. Although the victim was understood to have links to a bikie gang, a number of other motives were also being canvassed as part of police inquiries into the killing. Police said a man wearing a dark hooded top was seen walking from the area moments after the shooting.
