Four border crossings between Canada and western New York state were closed after a vehicle exploded at a tollbooth crossing into the US via Rainbow Bridge in Niagara Falls in what sources told Fox News was an attempted terrorist attack on Wednesday. Explosives were allegedly found in the vehicle, which was attempting to drive into the border officer building, according to the news outlet. The FBI’s Buffalo Field Office said it is investigating what it called a “vehicle explosion” in coordination with local law enforcement, describing the situation as “very fluid” in a post on X (formerly Twitter). Witnesses told local news outlet the Niagara Gazette that the car sped the wrong way into the border crossing’s inspection booths and exploded.
