South Korean media say U.S. Ambassador Mark Lippert has been attacked while giving a lecture and taken to a hospital for treatment.

Yonhap news agency said Lippert was injured, but it wasn't clear the exact nature of his injuries. YTN TV showed a picture of Lippert bleeding from the head and wrist but said his injuries weren't seen as life threatening. Calls to Embassy and police weren't immediately returned on Thursday. YTN said a man only identified by his surname, Kim, was arrested after the attack.

Lippert, 42, became ambassador last year and has been mostly popular during his time in Seoul. His wife gave birth here and the couple gave their son a Korean middle name. Lippert was formerly the U.S. Assistant Secretary Defense for Asian affairs.
