Five teens killed in Ireland M9 crash

Five teenage boys died in a head-on crash on Ireland's M9 motorway after their car was driven the wrong way, colliding with a family heading to Dublin Airport.

The crash killed all five occupants of the wrong-way car and seriously injured three women and a seven-year-old boy in the other vehicle.

Gardaí are investigating whether the teens were involved in a social media trend of filming dangerous driving.

The tragedy has sparked national debate about reckless driving and the role of social media in glorifying it.
