Two Buffalo firefighters had to be taken to a hospital for evaluation for minor injuries they suffered Thursday afternoon fighting a fire that caused $100,000 damage to two homes on Reservation Street in Black Rock.

The Red Cross helped five adults and four children who lived in the two apartments at 78 Reservation. The fire began about 4:30 p.m. in the rear first-floor apartment of that structure, Buffalo firefighters said.

The blaze, which remained under investigation late Thursday, caused $75,000 to the two-story frame apartment house and $15,000 in damage to the 2½-story frame house at 80 Reservation St., firefighters said.
