A car explosion on the American side of the Rainbow Bridge border crossing in Niagara Falls left two people dead on Wednesday and put authorities in both countries on high alert.

Canadian and U.S. border authorities say the Rainbow Bridge is back open as of Thursday evening, one day after a deadly car crash and explosion occurred on the American side of the border crossing.
