A pair of fires inside the city and out in Middlesex County kept firefighters busy Saturday.

The first call came in before 10 a.m.

A century old home on Charlton Dr. just east of Poplar Hill Rd. was fully engulfed when crews arrived.

No was home at the time, as it was unoccupied.

Although the fire proved to be stubborn.

"Flames were shooting out the main floor.  The floors had burned through, the main floor had burned through, so it was tough to get fire crews inside to actually attack this fire," says Chief Lonnie Fletcher with the Coldstream Fire Department.

Meanwhile, London emergency crews were called to 104 Clarence St. around 12 p.m. for a house fire.

Two firefighters suffered minor injuries, with a third one receiving second degree burns.

"Upon arrival, crews noticed smoke coming from the front window as well as the door. They made entry. At that point it appears the unit had flashed over and caused some injuries to some firefighters," says London Fire Inspector James Hind.

No one was home at the time of the blaze.

Damage is pegged at $125,000.

It is not considered suspicious.
