The Bureau of Alcohol, Tobacco, Firearms and Explosives has confirmed to WCPO's sister station in Buffalo, WKBW, that it is also investigating.
The vehicle explosion has closed all four border crossings in Western New York between the U.S. and Canada Wednesday afternoon. The Rainbow Bridge, Peace Bridge, Lewiston-Queenston Bridge and Whirlpool Bridge are all closed until further notice.
Photos and video taken by news organizations and posted on social media showed a security booth that had been singed by flames.
Further information wasn't immediately available.
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.
The others are Lewiston, Whirlpool and Peace Bridge. The Niagara Falls Bridge Commission reports all four crossings are closed.
