An 18-year-old woman and her younger twin siblings – a boy and a girl – have been killed after a “violent and traumatic incident” at a Dublin home.
Police officers were called to a property in the Tallaght area around 12.30am on Sunday.
Two children and a teenager were taken to Children’s Health Ireland (CHI) in Crumlin by ambulance, but all three were later pronounced dead.
A teenager was also transported from the scene to Tallaght hospital with serious injuries believed to be non-life threatening.

Gardai described it as a “violent, challenging and traumatic incident” but have not yet given further details on what happened.
The Garda Armed Support Unit used non-lethal means to apprehend a man in his early 20s at the scene.
He is currently being held at Tallaght Garda Station under Section 4 of the Criminal Justice Act 1984.
The children’s mother, who was unharmed at the scene, was also taken to CHI and is currently receiving medical attention.
Gardai said it is believed everyone involved knows each other and officers are not looking for anyone in connection with the incident.
The Rossfield Estate crime scene remains sealed and a forensic investigation by the Garda Technical Bureau will take place on Sunday.
It is believed that the teenager was 18 years old and the twins were eight years old.
The Coroner’s Office and the Office of the State Pathologist have been notified and an autopsy is scheduled to take place. A family liaison officer has been appointed and will continue to assist those involved, Gardai added.
Locals described being woken up in the early hours by police sirens and a helicopter blaring.
“I was up all night listening to the sirens and the helicopter. God loves them all,” said one woman.
Another resident wrote on Facebook: “Terribly sad. I could hear helicopter and police sirens last night.”
South Dublin County Council Councilor Charlie O’Connor described the incident as a “really sad event”. “Here in Rossfield you can get a feeling… that people are really shocked,” he told Sky News.
“We anticipated that this incident would have an impact on the community not only here in Brookfield but in the wider Tallaght area.”
There is a heavy police presence in the area while a full forensic investigation of the crime scene is ongoing.
The upstairs windows of the property were open and shattered, while bloodstains could be seen on the window frames.
A smashed ground-floor window also remained open while coroners examined the front yard.
A black car in front of the property was also the focus of the investigation.
Forensic officers removed a number of items from the crime scene, including a shoe, a small bag and a black coat, which were placed in forensic bags.
Flowers were also left at the scene. A floral tribute said: “Fly high, little angels. Our hearts are broken for you all.”
The streets surrounding the property remained busy with children playing nearby.
Helen McEntee, Ireland’s Minister for Justice, said: “The murder of three young family members is a tragedy, so terrible and heartbreaking. It is difficult to understand.
“My thoughts are with the family and the local community as they deal with this unimaginable crime.
“Gardai and other services are supporting them during this difficult time.”
Dermot Richardson, Sinn Féin councilor for the Tallaght area, called for welfare for the family, the local community and school children.
He also urged people to stop sharing video footage of the incident on WhatsApp and social media sites.
“Videos are shared on WhatsApp. I would like to ask people not to share them, also out of respect for family and local community,” he added.
“If you have footage, please pass it on to the Gardai.”
