LAWRENCE, Nassau County (WABC) --  A fire broke out at an elementary school on Long Island early Thursday.

Smoke poured from the building as firefighters moved in to get it under control.

It started around 3 a.m. inside the second floor of the Hebrew Academy of Five Towns and Rockaway on Washington Avenue in Lawrence.

"It was confined to one classroom, a large classroom," said Chief Edward Kohler, Lawrence-Cedarhurst Fire Department. "A little extension to the hallway, and a little extension to the outside of the building when the flames came out the windows."

Firefighters reported heavy smoke throughout the building.

"It was a textbook operation, the members did a really good job," Chief Kohler said. "They had smoke, they had to find the fire, there was a lot of hose stretching through hallways upstairs, and ultimately to the classroom that was on fire."

Fortunately, no one was injured.

There will be no school for students of the lower school Thursday.
