Mark Lippert, ambassador to South Korea was attacked as he was preparing to give a speech in Seol Thursday. He was formerly with the US department of defense but has been at his ambassadorial post in S. Korea since 2014.
AlJazeera reports his knife-wielding attacker "shouted anti-war slogans during a public event at an arts centre in Seoul."
Lippert was attacked during a morning breakfast conference.
The Korean TV News channel has posted video and photos of Lippert after the attack. There is blood on his face and he is holding his face with his left hand in the photos.
Shaky video showed a man with a beard (his face obscured) being wrestled to the ground. He is identified as Kim Ki-jong, aged 55. Kim has a former conviction for hurling a stone at a Japanese ambassador in 2010.
Kim is one of a small group of people in South Korea calling for unification of Korea; they want peace. Kim is reported as shouting "no drills for war" as he slashed Lippert.
Lippert was rushed off to a hospital for treatment. He was walking under his own power.
The ambassador was assaulted with a razor blade by the man who was opposed to the joint military exercises taking place with the US and S. Korea.
US embassy officials said Lippert is doing well following surgery and the ambassador himself tweeted a similar update.
