South Korean opposition leader Lee Jae-myung, who was stabbed in the neck by a man pretending to be a supporter, called for an "end to warlike politics" as he was discharged from hospital Wednesday.

Lee, chair of the Democratic Party, was surrounded by journalists in the southern port city of Busan on Jan. 2 when a man pushed through the crowd and lunged at him, stabbing him on the left side of his neck with a knife.

He suffered a wound to his jugular vein and was first taken to a hospital in Busan, then flown to the capital Seoul where he underwent a nearly two-hour surgery.
