US border explosion caught on VIDEO

Footage shows the vehicle accelerating before crashing into a checkpoint

Surveillance cameras at a US-Canada border crossing captured the moment a speeding vehicle exploded at a checkpoint on Wednesday. An investigation into the incident is still ongoing. 

CCTV footage posted to social media shows an explosion immediately outside a customs booth, though the car itself does not appear in that clip. Other footage described by news outlets including ABC and Fox News reportedly shows the vehicle stopping at an initial security checkpoint on the US side of Rainbow Bridge, which spans the Niagara River gorge, where it was referred to another checkpoint for closer examination.

The vehicle apparently sped up and crashed into the second checkpoint, where it exploded, according to another CCTV video.
