The three-alarm blaze broke out around dawn Thursday along the Lawrenceville Highway in DeKalb County.

DeKalb Fire spokesman Fred Johnson told The Atlanta Journal-Constitution that the warehouse held lighters as well as cigarettes and other items sold by convenience stores.

"Those products are made to burn, so that's why the building is burning the way it's burning," Johnson, who added that it would likely take the rest of the day to bring the fire under control, told the Journal-Constitution.

No injuries were reported and the cause has been traced to a storage trailer outside the warehouse, the newspaper reported.
