This is the best summary I could come up with:
Ron Rienas, general manager of the Peace Bridge, told CBC Hamilton the bridges were shut down on Wednesday afternoon.
On social media platform X, formerly known as Twitter, the FBI Buffalo account said: "The FBI Buffalo Field Office is investigating a vehicle explosion at the Rainbow Bridge, a border crossing between the U.S. and Canada in Niagara Falls.
The FBI is coordinating with our local, state and federal law enforcement partners in this investigation.
Kathy Hochul said on X that she "has been briefed on the incident on the Rainbow Bridge in Niagara Falls and we are closely monitoring the situation.
Kerry Schmidt said "we have major issues happening right now at the U.S. borders in the Niagara Region.
Right now we currently have the Rainbow Bridge closed in both directions in Niagara Falls.
The original article contains 252 words, the summary contains 128 words. Saved 49%. I’m a bot and I’m open source!
What a way more sensible and informative title.
TL;DR: A vehicle was incinerated down to the engine block. There is no evidence that it was terrorism, but they are assuming it was intentional pending investigation out of an abundance of caution. There is now heightened security at border crossings, but there are no known threats on either side of the border. Due to the extensive damage to the vehicle, the investigation is expected to proceed slowly. Other border crossings are open, but not the Rainbow Bridge.
