U.S. Ambassador to South Korea Mark Lippert was hospitalized Wednesday after he was attacked with a small razor blade at a public event in the country’s capital, ABC News reported. The suspect, who has not yet been identified, has been arrested. The incident is under investigation.

The ambassador was on his way to a “breaking meeting” in Seoul when the assault occurred, Agence France-Presse reported. Lippert reportedly is in stable condition.
