A young French boy's moving conversation with his father about the "bad guys" who carried out the terrorist attacks in Paris has resonated around the world.

The little boy, Brandon, and his father, Angel Le, were visiting a memorial outside the Bataclan concert hall to pay their respects to the victims when they were interviewed by French TV show Le Petit Journal.

The reporter crouched down beside the boy, who is about five, and asked if he understood what had happened in Paris, and why the the gunmen had carried out their attacks.

Brandon replied: "Yes, because they're really, really mean. Bad guys are not very nice. And we have to be really careful because we have to change houses."

Mr Le then attempted to reassure his son, as the camera continued rolling to capture their simple and moving conversation.

Mr Le said they would not move because "France is our home."

Brandon: But there's bad guys, daddy?

Mr Le: Yes, but there are bad guys everywhere.

Brandon: They have guns. They can shoot us because they're really, really mean daddy.

Mr Le: They might have guns, but we have flowers.

Mr Le told his son the flowers and candles that had been laid outside the concert hall were to protect them, and to remember the victims.

Brandon then broke into a small smile before telling the reporter: "I feel better."

Le Petit Journal posted the footage on its Facebook page, and it was shared 380,000 times in less than a day.

Mr Le posted a message on the media organisation's Facebook page, thanking people for their response.

"When I see all this support, it tells me one thing: I'm proud to be French and proud of my fellow countrymen!!! My family and I kiss you," he wrote.
