Stacks of fireworks…piled next to a rental truck…ignites…setting off a round of explosions at a Fourth of July block party in Toledo, injuring four people and littering a street with debris. A video from a neighbor shows people yelling and running for cover…as the fireworks exploded in every direction. At one point, the rental truck, which had been packed with the fireworks, briefly caught fire. The injuries aren’t life-threatening. State and local officials are investigating.
