Two people have died after a car explosion at a checkpoint near Rainbow Bridge, which connects the US with Canada, the Associated Press reported, citing local authorities. An eyewitness at the scene, Mike Guenther, said: 'We see this car coming down towards the border and he was flying over 100mph... he went up into the air and we've just seen a fire ball, that's all we could see, it was covered in smoke everywhere.'
