Kim Jong-nam killing: Footage emerges of airport 'attack'

CCTV footage from an airport Kuala Lumpur, Malaysia, apparently shows the killing of Kim Jong-nam, the half-brother of North Korea's leader Kim Jong-un.

He is believed to have been attacked in the airport departure hall last Monday by two women, using some form of chemical.

Police believe he was poisoned and are looking for four North Koreans.
