Border closed after explosion on bridge at Niagara Falls

Niagara Falls (US), Nov 22: A vehicle exploded at a checkpoint on the American side of a U.S.-Canada bridge in Niagara Falls Wednesday, prompting the closing of four border crossings in the area, authorities said.
The blast happened on the U.S. side of the Rainbow Bridge, which connects the two countries across the Niagara River. Three other bridges between western New York and Ontario were quickly closed as a precaution, and the Buffalo-Niagara International Airport began security checks on all cars and told passengers to expect additional screenings.
The Niagara Frontier Transportation Authority posted on X, formerly Twitter, that all cars arriving at the Buffalo Airport would undergo security checks. The authority said travelers should also 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 that it was investigating the blast, and investigators with the Bureau of Alcohol, Tobacco, Firearms and Explosives were also responding to the scene.
Photos and video taken by bystanders and posted on social media showed thick smoke, flames on the pavement and a security booth that had been singed by flames. (AP)
