Two people escaped a large fire at a home in Bell County Wednesday afternoon.

The man and woman told authorities they were asleep inside the home when the fire began.

Central Bell County firefighters said the blaze broke out around 1 p.m. at 3605 Setter Dr. in Bell County near Belton.

Bell County Fire Marshal Steve Casey said the fire was accidental. Central Bell County Fire Chief Jason Worsdale said the fire was caused by a water heater in a shed located at the back of the home.

Salado and Belton firefighters were called to help Bell County fire crews at the scene.

The Red Cross was assisting the pair Wednesday afternoon. Two of their cats died in the fire. Their dog survived and was with them Wednesday afternoon.
