Garda forensic scene investigators remain at the scene of a major road traffic accident on the N28 in Cork.
The collision, which involved up to four cars and a fully loaded car transporter, took place at the Shannon Park roundabout in Carrigaline at approximately 11am.
The occupants of one of the cars - a man and woman both understood to be in their 80s - were pronounced dead at the scene.
They have since been removed to the mortuary at Cork University Hospital (CUH).
A third person, the driver of another of the cars involved, was also taken to CUH for treatment following the incident.
His injuries are not described as life-threatening.
The drivers of the transporter and third car involved in the collision were both medically assessed at the scene, but did not require hospital treatment.
The truck is believed to have jack-knifed and flipped onto its side.
A huge multi-agency emergency response was launched following the collision.
Major traffic diversions are still in place to and from Ringaskiddy village, and to the Port of Cork terminal.
Gardaí have issued an appeal to anyone who may have witnessed this collision to come forward.
They are appealing to road users who were travelling on the N28 in the Shannon Park area between 10.45am and 11am with camera footage (including dash cam), to make it available to them.
