Two people have died after the vehicle they were in exploded on a bridge connecting the US and Canada, writes SkyNews.

The car crashed into a checkpoint on the US side of the Rainbow Bridge in Niagara Falls at high speed and caught on fire, according to Sky’s US partner network NBC News.

Senior law enforcement officials said there was no indication that a bomb was inside, as an initial search did not find a secondary explosive or device.

New York Governor Kathy Hochul said there was “no indication of a terrorist attack”. Authorities are trying to determine whether the crash was intentional, and the FBI has warned that the situation is “very fluid”. An initial assessment suggests the incident was caused by a reckless driver.

The Rainbow Bridge, which connects the two nations across the Niagara River, has been shut along with three other border crossings in the area.
