Children are being warned about the dangers of digging in sand dunes, after a teenager was killed when a tunnel collapsed around him.
The 16-year-old was on holiday in south west Wales playing with a group of around 15 friends when he got trapped.
Emergency services, including the coastguard and three fire engines, were called to Cefn Sidan beach.
Rescuers dug the boy out of the sand and he was flown to hospital in an air ambulance, but he sadly died.
The teenager from Wrexham in north Wales was on holiday with his family and friends when the accident happened at 7pm on Sunday.
Coastguard manager Dave Hughes said the huge tunnel in the sand had been big enough to walk through, but had become unsteady.

He said: "With school holidays in full swing we want to warn families to be aware of the dangers of tunnelling in sand.
"Wet sand as we have had today after rain makes it easier for tunnelling, but sand is always very unstable and heavy and can collapse at any time.
"Our sympathy goes out to the family following this tragic death."
