SEOUL, South Korea — A mystery woman's appearance with North Korea's young new leader is front-page news in South Korea. South Korean media are speculating that the young woman could be Kim Jong-un's younger sister or wife. North Korean TV Sunday showed a woman in a black jacket and skirt bowing with Kim at a ceremony marking the 18th anniversary of the death of his grandfather, North Korean founder Kim Il-sung. She is believed to be the same woman shown Saturday seated next to Kim at a concert. The North's Rodong Sinmun newspaper Monday ran a photo of Kim and the woman on its website. But North Korea released no details about her. — AP
