A 16-year-old boy has died after he was stabbed during a fight in Dublin last night.
Gardaí said it happened after a row broke out in East Wall at around 9:30pm last night.
Emergency services attended the scene and two boys were taken to the Mater Hospital with serious injuries.
One of them was later pronounced dead.
A third boy later presented at the hospital where he is now receiving treatment.
Cllr Anthony Flynn lives nearby and was one of the first on scene.
"I came out of my own home last night to see two young people who had been stabbed," he said.
"There was an allegation of the fact that somebody had stabbed two individuals who were on the ground.
"Obviously my thoughts and prayers are with the family. It was a heartbreaking situation last night to walk in to."
The scene on East Road remains sealed off this morning.
Investigators are appealing to anyone who was in the area between 9pm and 9:40pm last night to contact them.
They are particularly interested in speaking to anyone who may have dash cam footage.
Concerns about a rise in knife crime in the area had been raised at a Dublin City Joint Policing Committee just yesterday.
