Two young people lost their lives yesterday following separate road accidents.
A 19-year-old man was killed when his scrambler motorbike crashed in Dublin's north inner city.
And a five-year-old girl died after suffering extensive injuries in a motorway collision near Athenry, Co Galway, last week.
On Christmas Eve, a man in his 60s was killed when the car he was driving crashed on the M8 motorway near Cahir, Co Tipperary.
Those tragedies bring to seven the number of people killed on the country's roads in a week.
The victim of yesterday's motorbike accident, who was named by shocked neighbours as Leroy Coyle, of O'Sullivan Avenue, Dublin 3, was killed after he collided with a parked car on Ballybough Road near Croke Park.
The accident happened only a few hundred yards from his home.
The incident occurred shortly before 2pm, according to gardai, and Mr Coyle was rushed to the nearby Mater Hospital, where he was pronounced dead a short while later.
The two occupants of the parked car were uninjured.
A neighbour of the Coyles told the Irish Independent that Mr Coyle was the youngest of three children and had a brother and a sister.
It is understood that the family have been living at the house for around three years.
"I would know them from seeing them around. They seemed to keep to themselves, so I wouldn't have had much dealings with them. It's a very sad thing to happen though at Christmas," a neighbour said.
Several residents in the area where the crash occurred described how they were woken by the sound of scrambler motorbikes early on Christmas morning.
One resident said she witnessed up to three young people racing scrambler motorbikes without helmets. Another said she was fearful an accident would occur after watching several people race bikes though streets and said some of them drove on footpaths.
Local councillor Nial Ring, who knows the Coyle family, said the same bike involved in the fatal crash had been involved in an incident near Sheriff Street earlier on Christmas morning. A 20-year-old was hospitalised following that incident.
The issue of scramblers -- motorcycles designed for off-road usage -- being used in residential areas was raised at a recent joint policing meeting of gardai, local councillors and community representatives, according to Cllr Ring, who said: "The death is a tragedy for the whole community."
A section of the Ballybough Road remained closed for several hours yesterday as a technical examination was carried out. Gardai from Mountjoy station are investigating and have requested anyone with information to contact them.
Meanwhile, a five-year-old girl, who was injured in a three-car collision when her family car was blown off course by gale winds last week, also died yesterday.
The collision occurred on the M6 at Newford, Athenry, Co Galway. She was initially brought to University College Hospital, Galway, but then transferred to Temple Street Hospital in Dublin. Her life-support machine was turned off yesterday.
On Christmas Eve, one man died and another was injured when the car went off the M8 and struck a ditch near Cahir, Co Tipperary.
The driver of the car -- a man aged in his 60s, who is believed to be from Cork -- was pronounced dead at the scene.
On Monday, a man in his 40s was seriously injured in a collision in Loughrea, Co Galway. He was taken by ambulance to Portiuncula Hospital, where he was later pronounced dead. A nine-year-old boy travelling in the car at the time was also taken to hospital, but his injuries were not life-threatening.
On Sunday, Shane Donnelly (38) from Ballyjamesduff, Co Cavan, died after the car in which he was a passenger went into a lake near Strokestown, Co Roscommon.
The same day a 28-year-old man died in a single car collision at Youghal, County Cork.
And last Saturday, Aisling Maguire (23) died after a tree smashed on to her car on the road near Mullingar, Co Westmeath.
Meanwhile, in Northern Ireland, a man in his 50s died following a collision near Lisburn late on Christmas Eve. The PSNI is investigating.
Gardai have issued several warnings as the stormy weather continues to hamper driving conditions, with further high winds expected tonight.
