Twelve people were hurt yesterday evening when a food truck in Philadelphia exploded in a blast so powerful its propane tank landed 150 feet away. A mother and daughter who worked on the La Parrillada Chapina truck were critically injured with third-degree burns over more than 50% of their bodies, reports the Philadelphia Inquirer. Three other people burned in the explosion are in critical condition, and seven others suffered less serious injuries when flames briefly engulfed their vehicles, police say.
Surveillance video captured the moment the truck's propane tank exploded, creating a huge fireball that went all the way across the street, police say. The city's fire and police departments are investigating the blast. "We want to ensure that this was an accidental explosion. We want to ensure this wasn't anything criminal," a police spokesman tells the AP. "The bomb squad is investigating to see if there is any foul play."
