The incident on the U.S. side of the crossing led to the closure of four international border crossings and heightened security measures across the region.
Sources told CBS News and CTV News that the vehicle, travelling at high speed from the U.S. side, crashed into the customs station before exploding. The car was reportedly “charred beyond recognition,” complicating efforts to identify the victims or determine the cause of the explosion. Canadian officials are operating under the assumption that the incident might be terror-related, though other causes such as a medical event or reckless driving have not been ruled out.
