Suffolk County Fire, Rescue and Emergency Services Commissioner Rudy Sunderman said the fire will not be considered completely "contained" until 10-foot breaks are built around the full perimeter of the fire, where combustible materials and elements are removed to prevent it from reigniting and spreading.

An arson investigation is underway after a series of brush fires on Long Island in New York injured at least two firefighters as flames consumed hundreds of acres in Suffolk County over the weekend.

New York Gov. Kathy Hochul declared a state of emergency Saturday afternoon as dozens of fire departments responded to Long Island’s Pine Barrens to gain control of massive brush fires fueled by strong winds.

All four Long Island brush fires that sent soaring plumes of smoke into the air had been contained by Sunday afternoon, authorities said.
