SEOUL, South Korea (AP) — South Korea’s tough-speaking liberal opposition leader, Lee Jae-myung, was stabbed in the neck by an unidentified knife-wielding man who attempted to kill him during his visit to the southeastern city of Busan, police said.

Lee, 59, the head of the main opposition Democratic Party, was airlifted to a Seoul hospital for surgery after receiving emergency treatment in Busan. Police and emergency officials earlier said he was conscious after the attack and wasn’t in critical condition, but his exact status was unknown.
