Explosion on US-Canada Bridge in Niagara Falls Prompts Closing of Border Crossings

A vehicle exploded at a checkpoint on the American side of a U.S.-Canada bridge in Niagara Falls on Wednesday, prompting the closing of four border crossings.

The blast happened on the U.S. side of the Rainbow Bridge over the Niagara River. In addition to the subsequent closing of three U.S.-Canada bridge crossings, the Buffalo-Niagara International Airport began security checks on all cars and told passengers to expect additional screenings.

No further information was immediately available on the cause of the explosion. The FBI’s field office in Buffalo said in a statement it was investigating the blast in conjunction with the Bureau of Alcohol, Tobacco, Firearms and Explosives.
