Suspect Detained in South Korea Teacher's Stabbing; 14 Injured in Separate Attack

South Korean police have detained a man suspected of stabbing a high school teacher in Daejeon, while a separate random attack near a subway station in Seongnam left 14 people wounded. The suspect in the teacher's stabbing is described as a man in his late 20s, and the motive is still unknown. The attack in Daejeon occurred just hours after President Yoon Suk Yeol called for stronger law enforcement measures to restore public safety. The attack in Seongnam involved a car ramming onto a sidewalk before the driver began stabbing people at random. Two people are in life-threatening condition from that attack. South Korea has seen a rise in mass-stabbing cases recently, prompting calls for closer monitoring of social media and increased police presence.
