A father's emotional discussion with his young son about the Nov 13 Paris terror attacks in a live television interview has been circulated widely on social media.

The YouTube video, which has received close to a million views since it was uploaded on Monday (Nov 16), shows a reporter from Le Petit Journal speaking to the father-son pair at a memorial site outside the Bataclan concert hall, the scene of the bloodiest attack where 89 people lost their lives.

He asks the young boy, Brandon, if he understood what had happened, to which the boy replied in French: "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 house."

The boy's father, who was next to him, then jumped in to reassure him that he did not have to fear the "bad guys" as "France is our home".

"It's OK, they might have guns but we have flowers...It's to fight against guns, it's to remember the people who are gone yesterday," added the father, whom The Telegraph said was originally from Vietnam but is now living in Paris with his family.

Seemingly comforted by his father's words at the end of the interview, the boy said he felt better.
