South Korean netizens have flooded U.S. Ambassador to Seoul Mark Lippert's Twitter page with messages praying for his rapid recovery after the top U.S. envoy was attacked Thursday.

A knife-wielding assailant slashed Amb. Lippert's face and wrist at a breakfast function in central Seoul on Thursday. The ambassador was immediately taken to a hospital and received more than 80 stitches. Hospital officials said he will need to remain hospitalized for three to four days.

Hours after the attack, Lippert posted a message on his Twitter account saying, "Doing well & in great spirits! Robyn, Sejun, Grigsby & I - deeply moved by the support! Will be back ASAP to advance US-ROK alliance! Gachi Gapshida! (Let's go together!)"

As of Friday morning, the posting has drawn 19 Korean and English replies from netizens who wished him a fast recovery.

"You're a person who has generosity and doesn't care about trifle things. It will be a great honor for me if you go together with me," a netizen who use the ID Ohdeokhyeong Mumyeongshi, wrote in response to Lipper's posting.

"South Korean people really like you. I think a small number of extremists conducted a terrorist attack on you for their own benefits," another netizen "Kajamigun" said.

A netizen who identified himself as Lee Jun-ho said he apologizes as a South Korean citizen for the attack on the ambassador. "Hope you will get better day by day. Pray for you and your family," he wrote.

"I feel very sorry to this happened, and hope you get better soon," a netizen who used the ID "01411" said.

Also on Friday, the doctors treating Lippert said he was in good condition overall and is expected to have his stitches removed early next week. (Yonhap)
