South Korean soldiers have arrested a U.S. citizen attempting to swim across the Han River into North Korea. A Defense Ministry spokesperson told Agence France-Presse the man, in his 30s, was detained Tuesday night and handed over to the relevant authorities. “I was trying to go to North Korea in order to meet with Supreme Leader Kim Jong Un,” the American told investigators, according to an unnamed government source cited by South Korea’s Yonhap News Agency. Crossing the heavily militarized border between the two countries, which are officially still at war, is tremendously dangerous.
