North Korea boosts Kim Jong-un's security amid assassination threats

North Korea is increasing security for leader Kim Jong-un due to assassination threats, according to South Korea's National Intelligence Service. This includes deploying communication jammers and considering drone detection systems. Kim's public appearances have risen by about 60% this year. The North has also stopped using its "juche" calendar, which honored its founder, and is working to strengthen Kim's position as the sole leader. Kim's sister, Kim Yo-jong, has also made more public appearances, indicating a potential rise in her status. Concerns have grown about North Korea's military support for Russia in the Ukraine conflict. South Korean President Yoon Suk-yeol shared intelligence suggesting North Korean troops could reach the frontlines quickly, prompting calls for closer coordination with European nations.
