WACO -
Two Waco Firefighters were injured while trying to put out a house fire in South Waco Wednesday evening.
They were both treated at the scene for burns.
Firefighters were called to a home on 18-th Street, right off of I-35 southbound, around 6:30 p.m.
Two people were inside the house when the fire started, but they were both able to make it out safely.
Fire Investigators believe two small explosions started the fire. They say one happened in the front of the home and the other in the back. They don't know what caused the explosions.
