A two-alarm fire at an Anne Arundel County school Tuesday morning damaged several classrooms and took more than an hour to bring under control, county fire officials said.

Emergency dispatchers received a call about 5:40 a.m. for a fire at Eagle Cove School, in the 5100 block of Mountain Road in Pasadena. Investigators said the blaze started above a fourth-grade classroom near a heating and air unit inside the school's North Building. At least two other classrooms sustained water and smoke damage, according to a fire department spokesman.

Fire investigators have not determined a cause. No one was injured.

The elementary school, which was closed today because of the weather, was founded in 1956 and recently changed its name from Gibson Island Country School.
