A gas leak in a Lebanon home caused some problems for firefighters after the house went up in flames Tuesday morning. Lebanon fire crews responded to the scene on West Ash Street near 5th Street just after 4 a.m. Video shot at the scene showed the house fully engulfed in smoke with large flames coming from the roof. Firefighters said a burning gas meter briefly prevented them from fully extinguishing the fire. Crews evacuated surrounding homes as a precaution.
