A man was killed and a woman injured when they were struck by a vehicle while walking in Co Dublin last night.
The man, in his 60s, died of his injuries following the incident just outside Clondalkin.
The woman (17) was taken to hospital with serious injuries, that are not believed to be life-threatening.
They were struck by an SUV while walking in the vicinity of the 12th Lock bridge on the Newcastle road.
Two fire trucks and an ambulance went to the scene of the accident, which happened shortly before 9pm.
Gardaí from Clondalkin are investigating the incident and closed a section of the road last night. They have appealed for any witnesses to contact them.
It is the second tragedy involving two pedestrians in two days. In Louth, two women were killed after they stepped off a bus in Ardee. Josie Duff (79) was crossing the N2 at the Hunterstown Inn with her cousin Kathy McDonald (70) when they were struck by a car on Monday evening.
They had taken a bus to Dublin for Ms McDonald to attend a doctor's appointment, but were killed crossing the road on their return.
Mrs Duff, who lived on the Kells Road in Ardee, volunteered for local charities and organisations and has been credited with developing the Irish Wheelchair Association in her town. She was described as a "treasure" by locals.
The charity's service co-ordinator, Valene McMullen, said she campaigned for years and it has paid tribute to her by putting her name above the door in the main reception area of its centre.
"Josie was a treasure.
"If it wasn't for her, we wouldn't have this centre," said Ms McMullen.
"She was invaluable to the organisation, especially for her fundraising.
"She was so important to us that we named a room here after her.
"Neither Josie or her family needed the use of a wheelchair, but she campaigned for years for us. "She was just that sort of a person.
"She had a kind-hearted nature."
Ms Duff also carried out voluntary work for the local Ardee Hospice.
Its acting chairperson, Breda Lynch, said she had been a fundraising member for years.
"Josie worked tirelessly in her fundraising. She would always be there to help in any way she could.
"We are very saddened by her death, and her family are in all our thoughts and prayers," she said.
Former parish priest of Ardee Fr Michael Murtagh praised both Ms Duff and Ms McDonald, who lived on the Drogheda Road.
"Josie was, with her husband John, always happy and smiling, always elegant, positive and charitable.
"Kathy was a senior nurse manager in Moorehall Lodge nursing home for many years.
"She was reserved in manner, extremely professional and caring and her leadership qualities were obviously highly regarded," he said.
