A baby was inside the tent that was struck by a car after it veered off the road and crashed into campsite – leaving two people in a serious condition and seven others injured.
Clare Harris, who runs the Newgale campsite in Pembrokeshire, has said the baby is “okay” after the ordeal.
It is not clear if the child is one of those who required hospital treatment.
Two people are in a serious condition in hospital after a blue Ford Fiesta collided with a number of people and the tent shortly after 10.30pm on Saturday.
One person was airlifted to the University Hospital of Wales, the Welsh Ambulance Service said.
Four were taken by ambulance to Glangwilli Hospital, while one was taken to Morriston Hospital.
Ms Harris, who runs the campsite with her husband Mike, said: “The car was speeding down the hill, realised it needed to slow down and tried to brake.
“It flipped and rolled several times, and crashed into the tent.
“There was a young child, a baby, in the tent at the time, thankfully they are okay.
“It’s a tragic accident that the police are dealing with, that’s all we can say at the moment.”
The car is believed to have been travelling from the village of Roch towards St Davids when it crashed off the A487.
Dyfed Powys Police said passengers in the car were among those injured.
Police said in a statement: “The road was closed to allow investigations and reopened at around 7.45am today.
“Officers are appealing for any information regarding the vehicle, a blue Ford Fiesta, and its occupants.
“We are especially interested in any dashcam footage or doorbell footage which may have captured the vehicle being driven from Roch to the scene of the collision at Newgale.”
HM Coastguard in Broad Haven said: “The team were paged at 11.23pm last night to assist with multi-agency incident in Newgale.
“We organised a helicopter site and supported paramedics with casualty care.”
A Welsh Ambulance Service spokesperson said: “We were called yesterday at around 22:40 to reports of an incident at Newgale Campsite, Pembrokeshire.
“We sent six emergency ambulances, one duty operations manager, one Cymru high acuity response unit and our crews were supported on scene by the emergency medical and retrieval transfer service and search and rescue helicopter.
“One patient was flown to University Hospital of Wales, four patients were taken by road to Glangwilli Hospital, and one patient was taken by road to Morriston Hospital.”
