PHOENIX — Police are investigating the discovery of explosives in the
rubble of a burned structure that was among several buildings destroyed in two
blazes that broke out in an industrial area of west Phoenix.
The fires started Thursday night as the city was hit with the first dust storm
of the monsoon season that brought rain, lightning and winds gusting up to 50
It was not immediately clear what caused the fires, but authorities were
looking into lightning as a factor.
No injuries were reported, but police said an investigative team later found
dozens of tubes used for explosive devices at one of the sites with several of
them containing live munitions.
The investigation was continuing while authorities worked to determine what the
explosives were made of and who they belonged to.
