CCTV footage has emerged of what is allegedly the moment the half-brother of North Korea's leader was murdered in Malaysia.
It appears to show two women approaching Kim Jong-nam at Kuala Lumpur airport moments before he died a week ago.
Four people are being questioned and police say they are hunting other suspects, who are from North Korea.
Meanwhile Malaysia's Ministry of Foreign Affairs has summoned North Korea's ambassador to the country to explain his comments made over the death - after he suggested the possibility of a cover-up.
