Kim Jong Nam died last week after being assaulted at Kuala Lumpur International Airport with what was thought to be a fast-acting poison.

Grainy CCTV footage released by Japanese broadcaster Fuji TV on Monday appears to show Kim Jong-un being approached by a woman wearing white, who then puts both her hands over his face. He is later seen talking to police.

Reuters said it could not independently verify the authenticity of the videos, and police officials were not immediately available for comment.
