Twenty people were injured when lightning struck a beach in the US State of South Carolina Tuesday evening, officials said, NBC News reports.

Twelve children and six adults were taken to local hospitals, while two people left on their own after the strike at a beach near Lake Murray, Lexington County spokeswoman Vanessa Diaz said.

The patients’ ages were not immediately clear; neither was the extent of their injuries, Diaz said. The injuries are considered non-life-threatening.

The lightning struck on what was an otherwise “super hot and sunny” day, though a storm cloud did pass over the area, Diaz said.

“It didn’t rain or anything like that; it was just a random storm cloud that went by,” she said.
