Officials in China are scratching their heads following a mysterious van explosion. The car was travelling on an expressway in the Zhejiang Province when it collided with a truck parked on the side of road. Surveillance video shows the van, carrying paper and paint products, blowing up on impact. The stationary truck, as well as much of roadway, is engulfed by the flames. Neither driver was injured. Residents living near the accident site reported that their windows were rattled.
