Mobile firefighter crews battled two fires early Friday morning.
The first was on Park Avenue North, and a short time later firefighters also responded to a fire on Gaston Street.
The second one came at about 5 a.m., with units arriving on the scene of a residential fire in the 300 block of Gaston Street. That's between Basil Street and Adams Street. Mobile Fire-Rescue reported heavy flames were visible from the front of the single-story, duplex-style structure.
Firefighters were able to extinguish the flames.
MFRD spokesman Steven Millhouse told FOX10 News on the scene that the primary search of the home's interior was clear, with no one inside the structure.
The vacant structure suffered significant flame and water damage, and an investigation into the cause of the fire is pending, Millhouse said.
