Five days after the family’s visit, rangers identified the object as a 70-year-old unexploded WWII mine. A bomb disposal unit was immediately called in and carried out a controlled detonation, which was captured on dramatic video.

The children’s father, Gareth, shared the shocking discovery on social media, joking that the “buoy” his kids had been playing on turned out to be a wartime bomb. Kelly later admitted how close they had come to tragedy, calling the experience “shocking.”

Officials temporarily closed the beach and apologized for the disruption, stressing that safety measures were taken as quickly as possible. The incident serves as a stark reminder that dangerous remnants of past wars can still be hidden in ordinary places today.
