Fire damaged and forced the evacuation of a Brunswick hotel in frigid temperatures Monday morning.

The Americas Best Value Inn at 215 Pleasant St. reported a structure fire around 8 a.m. and evacuated its guests, said Fire Capt. David Hunter.

Firefighters found a bathroom vent had caught fire in a first-floor room and spread to a room next door, Hunter said. The fire was out within 20 minutes.

Damage appeared to be limited to two first-floor rooms and two rooms above them, he said. No injuries were reported.
