The top envoy to Seoul has been recovering from wounds on his face and wrist after being slashed by the man during a breakfast forum in Seoul last week. The  assailant said he did so in opposition to the Seoul-Washington joint military exercises.

"Thanks for all of the friendship and support! Means so much to the Lippert family! Back to work later next week," he said on his Twitter account, uploading two photos with his wife, son and dog.

He made his first public outing on Friday since being released from the hospital three days ago by attending a dinner party for the U.S. Forces Korea hosted by a local research foundation, Gumgok.

The attacker, named Kim Ki-jong, has been under probe after being arrested last week on charges of attempted murder, violence against a foreign envoy and business obstruction. (Yonhap)
