 An ammunition exploded inside a home during a house fire in the Indian Trail neighborhood last night. Spokane firefighters say they found shell casings littered on the street outside the home. Thankfully, no one was injured. There was a dog inside the home, but firefighters were able to get it out safely. Spokane Fire Battalion Chief Abel Gonzalez says the hot weather made it more difficult to fight the fire. The department's arson investigator is working to figure out a cause.
