Border crossings closed after vehicle explosion on bridge connecting New York and Canada

Authorities say a vehicle has exploded at a checkpoint on the American side of a U.S.-Canada bridge in Niagara Falls. Four border crossings in the area are closed as a result. The FBI’s field office in Buffalo said in a statement that it was investigating the explosion Wednesday on the Rainbow Bridge, which connects the two countries across the Niagara River. Photos and video taken by news organizations and posted on social media showed a security booth that had been singed by flames. Gov. Kathy Hochul said she had been briefed on the incident and was “closely monitoring the situation.” The Rainbow Bridge is one of four border crossings connecting Ontario to western New York.
