South Korea sentenced a man who stabbed the U.S. ambassador to 12 years in jail for attempted murder on Thursday. Kim Ki-jong, 56, attacked U.S. Ambassador Mark Lippert at a Seoul hotel in March. Lippert required 80 stitches in his face and his hand was left scarred. Kim, a known Korean nationalist who had thrown concrete at the Japanese ambassador in 2010, said he was protesting against joint military exercises between the U.S. and South Korea. He said he did not intend to kill Lippert, but the prosecution argued the attack was meant to be fatal and sought a 15-year prison term. The Seoul Central District Court said he had "shown no repentance, attempting to justify his actions throughout the trial."
