US civil rights leader Jesse Jackson and Jean-Marie Le Pen were feuding on Twitter Wednesday after the French far-right firebrand posted a picture of them together at a Paris restaurant, AFP reports.

Le Pen on Tuesday tweeted a photo of the two men at a Moroccan restaurant, along with a note apparently handwritten by Jackson reading: "May 8-'16. Jean-Marie, (wife) Jany Le Pen, Keep Hope Alive, Continue".

But Jackson said he had unwittingly dined with the French politician on Sunday, tweeting: "Did not know you were coming to dinner. Never met you before. Do not share your beliefs."

"Keep Hope Alive" was a catchphrase the Baptist minister used during his unsuccessful 1988 bid for the US presidency.
