The leader of South Korea's political opposition was stabbed at a news conference in the southern port city of Busan.
Lee Jae-myung, who narrowly lost the presidential elections in 2022, was stabbed on the left side of his neck on Tuesday morning, reports BBC.
The male attacker was arrested at the scene.
Lee was transferred to a hospital about 20 minutes after the attack. He was conscious at the time.
The attacker appeared to be in his 50s or 60s. He reportedly approached Lee asking for an autograph, before suddenly lunging forward to stab him.
Videos of the attack on social media show Lee first collapsing into the crowd and then onto the ground, while several people try to restrain the attacker. Photographs after the incident show Lee lying on the ground with his eyes closed while someone presses a handkerchief to the side of his neck.
Lee, 59, leads the Democratic Party of Korea. He is not currently a member of South Korea's legislature but is widely expected to run for a seat in the next general election, which will take place in April 2024.
