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: 

We are closely monitoring the situation at Rainbow Bridge in Niagara Falls and have reached out to local authorities to provide assistance.

We are praying for the safety of Customs and Border Patrol and the first responders answering the calls for help. https://t.co/wrngD77MTD

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.
