At least two people were reported killed after fireworks set off an explosion in a residential area of Ontario, California on March 16.
Shortly before 1 pm local time, the Ontario Fire Department tweeted that multiple units were responding to a “reported explosion.”
Officials with the City of Ontario later tweeted that fireworks were responsible for the explosion, and additional explosions were due to residual fireworks being set off.
