Footage has emerged apparently showing the assassination North Korean dictator Kim Jong-un's half brother in Malaysia's main international airport.
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.
Last week two female suspects, one an Indonesian and the other carrying Vietnamese travel documents, were arrested, while a Malaysian man was also been detained.
At least four more suspects are believed to be at large.
Reuters said it could not independently verify the authenticity of the videos, and police officials were not immediately available for comment.
Malaysia's The Star reports four suspects in the assassination are believed to be back in Pyongyang, after leaving the country for Jakarta immediately after the attack.
The paper reports that after the attack, they flew from Jakarta to Dubai and Vladivostok before reaching Pyongyang.
Kim Jong-Nam, 45, was the eldest son of late North Korean leader Kim Jong-Il, and had lived in Macau, China, since about 2007.
