Five people in their 20s died in a road crash in Co Louth on Saturday night.
Irish police said three others were injured in the two-vehicle crash, which they have described as “shocking and devastating”.
An investigation has begun into the accident on the L3168 at Gibstown, just outside Dundalk.
Speaking near the scene on Sunday, Superintendent Charlie Armstrong said: “Yesterday evening, just after 9pm, there was a serious road traffic collision involving two vehicles, a Volkswagen Golf and a Toyota Landcruiser.
“Five occupants of the Volkswagen Golf, three males and two females, all in their early 20s, are deceased at the scene.”
Mr Armstrong said a man in his 20s in the Volkswagen and a man and woman from the other vehicle were taken to Our Lady of Lourdes Hospital, Drogheda, for treatment.
He said family liaison officers have been appointed to each of the families and gardai will keep them updated.
Mr Armstrong said: “I want to express my condolences and sympathies and the sympathies of every member of An Garda Siochana to the families of the five young adults who lost their lives yesterday evening in this road traffic collision.
“Last night members of An Garda Siochana, supported by other emergency services including Dundalk Fire Brigade, HSE paramedics and staff at Our Lady of Lourdes Hospital, Drogheda, initiated a major incident response.
“The scene here on the L3168, Gibstown, remains closed today and a technical and forensic examination is being carried out by An Garda Siochana forensic collision investigators.”
He said post-mortem examinations would be carried out.
