The United States ambassador to South Korea was attacked on the streets of Seoul, Thursday morning Korean time.
Appearing on CNN, State Department spokeswoman Marie Harf said Mark Lippert is now in the hospital and officials have yet to determine a motive.
"We will do a full investigation," Harf said, adding that the "injuries are not life threatening."
Images on Korean television showed Lippert walking away from the scene holding his right hand over his right cheek and blood splattered over his other hand and face. The video shows Lippert leaving a building and walking into a police car.
In a statement, the State Department said Lippert was attacked while giving a speech.
"We strongly condemn this act of violence," State said.
