South Korea boosts security for opposition leader over threats

South Korean police have increased security for Lee Jae-myung, the leader of the main opposition Democratic Party. This decision comes after concerns were raised about a potential assassination plot against him. The Democratic Party alerted the police following warnings from some lawmakers. Last year, Lee was attacked when a man stabbed him in the neck while asking for an autograph. The assailant received a 15-year prison sentence for the incident. Tensions are high in South Korea following a political crisis triggered by President Yoon Suk Yeol's brief imposition of martial law last December. This has deepened divisions between conservatives and liberals in the country. Yoon is currently facing a criminal trial for insurrection, and the Constitutional Court is expected to issue a ruling soon that could lead to his impeachment. Police are preparing for possible clashes as both supporters and opponents of Yoon plan large rallies around the court's decision. Acting President Choi Sang-mok urged citizens to accept the court's ruling. In January, supporters of Yoon violently protested, storming a court building and causing damage.
