A vehicle exploded on Wednesday at the Rainbow Bridge connecting the United States and Canada at Niagara Falls prompting authorities to close all four border crossings between western New York and Canada, U.S. and Canadian officials said.
The FBI Joint Terrorism Task Force was mobilized to investigate the incident, according to New York Governor Kathy Hochul.
Two people in the vehicle were killed in the blast and one border patrol official was injured, the Fox News Channel reported, citing unnamed sources. CNN also reported that two people died in the explosion.
No explosives were found in the car, an NBC reporter stated on X, citing four unnamed law enforcement sources.
Reuters was unable to immediately verify these reports.
Eyewitness video showed heavy smoke rising from the area.

Official details of the incident were murky. The Niagara Gazette newspaper, citing law enforcement sources, said the car sped onto the bridge plaza, went through a fence separating the inbound lanes from the outbound lanes, and toward the inspection lanes, where it exploded.
The Rainbow Bridge and the three other border crossings between western New York and Canada - the Peace Bridge, the Lewiston-Queenston Bridge and the Whirlpool Bridge - were shut down indefinitely as a precaution, the New York governor's office said. Additionally, Buffalo Niagara International Airport was closed to departing and arriving international flights following the incident, the US Federal Aviation Administration (FAA) said on their website.
The three U.S.-Canada crossings along the Niagara River separating southern Ontario and New York state are among the busiest in the world.
Security measures were escalated at airports and railways in the region managed by the Niagara-Frontier Transit Authority, the governor's office said.
"This is obviously a very serious situation. The government of Canada is taking this situation extremely seriously," Public Safety Minister Dominic LeBlanc told reporters in Ottawa. "We are in close contact with American authorities. I will be speaking with the US Homeland Security secretary shortly," LeBlanc said.
FBI, Canadian officials investigating
The explosion was under investigation by agents from the FBI field office in Buffalo, New York, the agency in a statement on the social media platform X, formerly known as Twitter.
"The FBI is coordinating with our local, state and federal law enforcement partners in this investigation," the FBI statement said. "As this situation is very fluid, that's all we can say at this time."
Hochul issued a separate statement on X saying, New York state police, at her direction was "actively working with the FBI Joint Terrorism Task Force to monitor all points of entry to New York."
Law enforcement teams in Canada also were "actively engaged in assessing the situation," Ontario Premier Doug Ford said in a post on X.
Border agency officials in the United States had no immediate comment, while their Canadian counterparts did not immediately respond to a request for comment.
Representatives for the U.S. State Department also did not immediately respond to a request for comment on the reported border closures.
The White House was closely monitoring the situation, as well, a spokesperson said.
New York Governor Kathy Hochul said on X that authorities in New York state are "closely monitoring an incident on the Rainbow Bridge in Niagara Falls and state agencies are on site and ready to provide assistance."
