PARIS - The world must brace for a long war between Russia and Ukraine after Moscow launched an invasion of its pro-Western neighbour, French President Emmanuel Macron warned on Saturday.

“I can tell you one thing this morning it is that this war will last,” Macron’s told France’s annual agriculture fair.  “This crisis will last, this war will last and all the crises that come with it will have lasting consequences,” Macron added, warning: “We must be prepared”.

Macron cut short his visit to the agriculture fair, usually one of the main fixtures on the French political calendar, in order to return to dealing with the crisis triggered by the Russian invasion.
