Nine firefighters were injured and multiple buildings destroyed after a huge explosion in Seattle on Wednesday morning.
The cause of the blast is still under investigation, but there's speculation a gas leak the firefighters responded to about 40 minutes earlier could be to blame.
Dozens of emergency personnel rushed to the northern Greenwood neighborhood as nearby residents were evacuated.
"We could smell the gas before, and you could hear it hissing, but at that moment, I was thrown on the ground," a KOMO news photographer said.
Local media outlets report the explosion aftermath included "glass ... raining down," and hours later, there were still some fire flare ups.
