Richard Arnold: US Correspondent on the explosion on Niagara Falls' Rainbow Bridge on the US-Canada Border - The Mike Hosking Breakfast

Niagara Falls' Rainbow Bridge is set to reopen tomorrow after the car explosion on the US-Canada border. 

Two people were killed when their car sped up and flew into a security checkpoint from crashing into a pylon. 

Authorities were initially on high alert with terror-related fears due to the mass travel ahead of Thanksgiving. 

US correspondent Richard Arnold told Mike Hosking that they have since determined it wasn't terror related. 

He says the two victims, a New York couple, were heading to a KISS concert.
