A Hawaii national park has issued a new warning to tourists after a toddler was grabbed “in the nick of time” from falling off the rim of an erupting volcano.

The little boy wandered off from his family and “in a split second, ran straight toward the 400ft cliff edge” of the Kilauea volcano, the park said.

“His mother, screaming, managed to grab him”, the park added in its statement, when the toddler was “just a foot or so away from a fatal fall”.

Park ranger Jessica Ferracane, who observed the incident, told the BBC she hopes sharing details of the incident will help “prevent future tragedies”.
