Footage of the attack on Kim Jong-nam, the half-brother of North Korean leader Kim Jong-un, has been posted on YouTube.

The video shows a woman approaching a man—presumably Kim Jong-nam—from behind, holding his head for several minutes, and then leaving in another direction, according to RIA Novosti news agency of Russia.

Subsequently, the attack victim approaches security service officers, shows his face, and, subsequently, they together head toward a medical center.

The attack on Kim Jong-nam was carried out on February 13 at Kuala Lumpur airport in Malaysia, from where he was to travel to Macau to be with his family.
