SELLERSBURG, Ind. (WHAS 11)--A fire in Sellersburg forced two people out of their home.

The fire happened a little after 3:45 a.m. Tuesday on Diana Drive and Country Line Road.

A diesel truck parked behind the home exploded. Investigators said they're not sure if the explosion caused the fire or if the fire spread from somewhere else and caused the explosion.

A neighbor heard the sound, woke the family up, and helped them get out of the home.

"We owe a lot to the neighbors who are vigilant in their neighborhoods and look out for each other. That was the story today, and thankfully everybody made it out safe," New Chapel Fire Department Captain Matt Owen said.

The family has lived in this house for 28 years and said they're so grateful for their neighbor helping them get out of the house.

Investigators said the home has a lot of damage in the back, but isn't a total loss.
