A child has died after being thrown from a bouncy castle that eyewitnesses say exploded on a Norfolk beach.
The girl was thrown from the inflatable at Gorleston beach at about 11:00 BST and paramedics took her to James Paget Hospital, but she died of her injuries.
Norfolk Police have cordoned off a section of the beach, which was busy with people enjoying the hot weather, to begin an investigation.
The inflatable was on Lower Esplanade in the children's play area.
Eyewitnesses said it "exploded" and the child was thrown into the air.
The East of England Ambulance Service Trust (EEAST) said it received more than a dozen calls to the incident and several people, including the RNLI, came to the aid of the girl.
Paramedics were on scene within four minutes, when the girl was in cardiac arrest, and she later died.
