Kim Ki Jong, representative of the Uri Madang, a civic organization demanding peace against war, suddenly stormed with a knife Mark, shouting the south and the north must be reunified and he is opposed to a war.

Mark was rushed to a hospital for his serious wounds on his face and hand.

Kim has the precedence of pelting brick at the Japanese ambassador to south Korea in July 2010 who cried out for "prosperity common" to south Korea and Japan, only to be sentenced to prison terms.

He didn't stop shouting slogans opposing war and the U.S.-south Korea joint military exercises, being walked away by police.

KBS, CBS, MBC and other broadcasting services of south Korea reported the news, screening Mark shedding blood from his face and wrist.

The AP and other foreign news agencies promptly aired the breaking news.

CNN, quoting south Korean media as reporting Kim was opposed to the joint military exercises, said that his remarks were prompted by his anti-American feelings.

The puppet police are strictly guarding U.S.-related facilities allegedly to cope with emergency.

The recent case amid mounting anti-Americanism reflects the mindset of south Korean people censuring the U.S. for bringing the danger of a war to the Korean peninsula through the madcap saber-rattling.
