Authorities say fireworks sparked a fast-moving forest fire that has consumed thousands of acres in southern New Jersey.

The New Jersey Forest Fire Service said Sunday that “a fireworks device” set alight in the Wharton State Forest late on the Fourth of July started the fire.

The blaze was spotted from a fire tower shortly after 9 a.m. Friday burning near Apple Pie Hill and the Batona Campground, which was evacuated as a precaution.

Officials asked anyone with information about the fire to call the state park police tip line.
