Three people were killed and six were injured when they were struck by lightning (search) at a park Sunday.

The nine were on a tree-lined walkway connecting a beach to a parking lot when lightning hit a tree at Buford Dam Park (search) on Lake Lanier, a spokesman for the Gwinnett Police Department said.

Two men and a woman died instantly, Gwinnett fire spokesman Thomas Rutledge said. Six others were taken to area hospitals; none suffered life-threatening injuries, according to hospital officials.

The group was visiting the park about 35 miles northeast of Atlanta (search) when a major storm hit and forced everyone there to leave the water.

The names of the victims had not been released late Sunday.
