A schoolboy has died after falling off rocks into the sea while on a family holiday.
Emergency services were alerted to reports of two males in the waters in Llangennith, Swansea.
It is understood the incident unfolded after a 15-year-old fell off rocks and his older brother jumped into save him.
They had reportedly been fishing at Blue Pool corner with two other friends at the time.
A South Wales Police spokesman said: "We responded to reports of two males in the sea at Llangennith, Swansea, at around 8.20pm on Wednesday August 1.
"They were taken by helicopter to Morriston hospital where one of the males, aged 15, was pronounced dead.
"The other male, aged 21, remains in hospital."
While the pair's identities have not been released, it is understood they came from the north west of England.
Swansea Coastguard said it had called out the Rhossili Coastguard rescue team, the Loughor independent rescue boat, Burry Port RNLI inshore lifeboat and the Tenby RNLI all-weather lifeboat and a rescue helicopter.
One brother was picked up by Burry Port lifeboat and the other was winched from the water by the helicopter.
