North Korean state TV showed images of leader Kim Jong-un attending a musical performance on Saturday next to a short-haired woman who seemed to be in her 20s and may be his sister.
North Korea experts believe her to be Kim's younger sister Yeo-jong. Born in 1987, Yeo-jong is now in her mid-20s. She apparently went to a school in Switzerland along with Jong-un in the 1990s. Others believe the woman is Kim's wife.
