‘No sign of terror activity’ in car explosion on Rainbow Bridge says New York governor

Four border crossings between the US and Canada were closed after a vehicle exploded at a checkpoint on a bridge near Niagara Falls, reportedly killing two people. Kathy Hochul, the governor of New York, said there was ‘no sign of terrorist activity’ in the explosion which happened on the US side of the Rainbow Bridge, which connects the two countries across the Niagara River. 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 fireball. That’s all we could see … It was covered in smoke everywhere’
