New York Governor Kathy Hochul said on Wednesday that, at this time, there is no sign that the car explosion at the Rainbow Bridge in Niagara Falls was terror-related.

"At this time, there is no indication of a terrorist attack," Hochul told reporters. "Let me repeat that: At this time, there is no indication of a terrorist-involved attack here at the Rainbow Bridge in Western New York.”

The FBI is investigating the vehicle explosion at the Canadian border that left the two people in the vehicle dead, according to NBC News.

At least one of the two people in the car was from Western New York and the speeding and ensuing crash all happened on the US side, contrary to some early reports that the vehicle had come from Canada.

Hochul said she's seen video of the car that was going at an "extraordinarily high rate of speed" before it went flying in an "absolutely surreal" scene.

"When you see this video, your jaw will drop in disbelief at how this went so high, over an 8-foot-high fence," she told reporters.

A Customs and Border Protection officer suffered minor injuries that did not require hospitalization, said a senior law enforcement official quoted by NBC News.

Authorities are investigating whether the crash was intentional.

All western New York bridge crossings into the U.S. were shut down following the incident, the Erie County executive said shortly after the crash, but Hochul later said all bridges were back open.

New York City Mayor Eric Adams said security has been increased and the "city is on heightened alert due to the upcoming holiday."

The White House is also closely monitoring the situation, an official said. The Canada Border Services Agency said it was "liaising with our US counterparts on this matter."
