Ontario explosion: Witness videos show fireworks igniting, massive smoke plume

ONTARIO, Calif. (KABC) -- A house full of fireworks exploded in Ontario Tuesday, setting multiple structures on fire. At least two people were killed in the incident.

The huge blast was felt and seen for miles. Residents as far away as Anaheim and Huntington Beach reported feeling the explosion. Eyewitnesses captured the dramatic explosion as it unfolded.

The massive explosion happened around 12:30 p.m. in the 400 block of West Francis Street, shattering nearby windows and sending a huge plume of smoke into the air.
