SPOKANE, Wash. -

An apartment fire in north Spokane claimed the lives of two adults Wednesday evening and seriously injured one firefighter.

The fire began around 4 p.m. at the Rosewood Club Apartments in the 400 block of East Magnesium. Officials have not released the names of either victim or the injured firefighter.

Some residents who were home when the fire began reported seeing smoke, then hearing an explosion.

"I let all my neighbors know to get out," said Brian Tozier, who was on his deck grilling when he saw the smoke.

Firefighters arrived at the scene, and one of them rushed into the unit where the fire began to save anyone who was inside. It was during that daring rescue that the fire took a turn for the worse.

"The fire flashed, large amount of heat, products of combustion rushed toward the firefighter who was making the rescue and did result in pretty significant thermal burns to his upper torso," said Assistant Fire Chief Brian Schaeffer.

That firefighter is in serious condition at Sacred Heart Hospital. A man and a woman who were inside that unit did not survive.

Other residents are now left picking up the pieces from the destruction.

"From the look of it, I'm guessing it's a complete loss," said Alexander Knox while discussing his apartment unit. "Everything we both had in there is in there."

Knox wasn't home when the fire began. He was on his way back from shopping, when he got a phone call.

"I got a call from one of my really good friends and she said 'hey it looks like there's something on fire over there. It may be your apartment,'" he said.

While Knox wasn't home, his boyfriend was. Knox said he rushed home, to find his boyfriend was out of the apartment safe. But, for this couple, the fire doesn't come with good timing.

"We're celebrating our one year anniversary. But I just have to keep thinking that it's okay," he said. "We have each other."

Others who live in the unit say they're just happy to be alive.
