A 17-year-old boy has died after a crash in Clondalkin, Dublin.
Gardai are appealing for witnesses following the fatal collision on the N7 at Naas Road.
The crash involving a car and a van occurred at approximately 12.30am on the westbound lanes of the dual carriageway.
The driver and sole occupant of the car, a boy aged 17, was pronounced dead at the scene a short time later.
His body has since been removed to the mortuary at Tallaght Hospital.
It is understood the car involved had come to the attention of gardai in Tallaght shortly before the collision and a referral has been made to An Garda Siochana Ombudsman Commission (GSOC).
The occupants of the van, two men aged 45 and 36 and a nine-year-old boy, were taken by ambulance to Tallaght Hospital.
Their injuries are not thought to be life-threatening.
Garda forensic collision investigators have examined the crash site and both vehicles involved and the road has since fully reopened to traffic.
The coroner has been notified of the death.
Investigating gardai are appealing for witnesses and in particular to anyone with camera footage to make it available to them.
