Fast-moving brush fires fanned by high winds burned through a large swath of land on New York's Long Island on Saturday, spewing thick gray smoke into the sky and prompting the evacuation of a military base and the closure of a major highway.

Officials said three of the four fires were fully contained while the other one, in Westhampton, was 50% contained. Two commercial buildings were partially burned, but officials said homes were not in the line of fire. One firefighter was flown to a hospital to be treated for burns to the face.

New York Gov. Kathy Hochul declared a state of emergency Saturday after several wind-driven brush fires broke out in New York’s Long Island, sending large smoke plumes into the air and shutting down a highway.
