FRENCH president Emmanuel Macron today revealed there were contingency plans in place to move the opening ceremony for the Paris Olympics from the River Seine if the security threat is deemed too high.

With just over 100 days to go until the start of the Games, there is concern among the French public about the possibility of a terrorist attack.

Around 10,500 athletes are set to parade on boats along a 3.7-mile route through the heart of the French capital on July 26 in the first Olympic opening ceremony held outside a stadium setting.
