The Boston Fire Department reports a child playing with matches at 24-26 Hopkins St. started a fire around 4:30 p.m. on Saturday that did an estimated $75,000 damage.

None of the occupants of the three apartments were injured, but the department says a dog and a cat did not make it, despite efforts of firefighters to revive them with oxygen. Ten people were made homeless by the fire.

The department says the child started the fire in a first-floor bedroom of the 2 1/2-story building.
