Six people - including five teenagers - have died following a stampede at a stampede in Italy.
It's understood people at the event in the north-eastern town of Corinaldo panicked and ran for the exits when someone sprayed a substance.
Three girls and two boys aged between 14 and 16 were killed, alongside a mother who'd accompanied her daughter to watch an Italian rapper.
Around 35 others have been injured - 12 of them seriously.
Government ministers pledged an investigation to identify anyone responsible for the incident.
Emergency services, meanwhile, posted images of firefighters and medical staff at the scene:
