Firefighters in New York have knocked down a dwindling brush fire in a wooded stretch of Long Island but officials say high wind gusts could leave the region vulnerable to additional blazes.

All four Long Island brush fires that sent soaring plumes of smoke into the air had been contained by Sunday afternoon, authorities said. Two firefighters were hurt battling the blazes and two commercial buildings were damaged, Newsday reported. No residential buildings were damaged; any earlier reports of burned homes were erroneous.
