There are breaking reports of an explosion at the Rainbow Bridge entering the U.S. from Canada at Niagara Falls. 

It reportedly closed access in both directions. 

The Rainbow Bridge has been closed to all traffic amid reports of a vehicle explosion just outside the border inspections plaza on the American side.

Traveling down Niagara Street, the car reportedly sped the wrong way into the inspection booths, where the explosion occurred.

Representative Claudia Tenney (R-NY) also issued a statement on Twitter/X regarding the incident: 

A visitor from Ukraine who was with a friend said they saw the vehicle speed toward the bridge and then observed what appeared to be the same car on fire near the entrance to the bridge.

"We heard something smash," he said. "We saw fire and big, black smoke."

This is a developing story, so we will be updating as we receive more information.
