2 people are in critical condition this morning after a food truck exploded in Philadelphia.
The Tuesday night explosion injured 10 others.
Witnesses describe it as a quick, violent blast.
One woman says she has a 1st degree burn on the left side of her body.
She says she was just walking by when the truck blew up , fire hit her, and she just ran.
Other witnesses saw parts of the truck and a propane tank fly across the street, setting a passing car on fire.
Right now, it seems the blast started with the propane tank.
