Rumors are flying about North Korean dictator Kim Jong Un's health and prompting questions about who might succeed him if he dies.
US intelligence reportedly indicates that Kim recently underwent heart surgery and could even be incapacitated. The South Korean government denied the reports, but that hasn't tamped down the speculation.
Few political figures have drawn such intense curiosity as the secretive Kim Jong Un and the people believed to make up his family tree.
Kim has become the face of North Korea to the world in recent years in light of his missile testing and bombastic feuds with President Donald Trump. But he comes from a line of Communist Party dignitaries and North Korean heads of state that stretches back to the end of World War II.
Like his father and grandfather, Kim keeps key details about his family withheld from the public, giving few clues about the lives of his wife and young children. But the penchant for privacy hasn't stopped international media and South Korean intelligence from attempting to learn all they can about him.
Some North Korea observers, such as the American website NK News, have even speculated that it's unlikely a family member would take over, and instead one of the top leaders of the Workers' Party of Korea would step in after a power struggle.
While the world speculates about his health and line of succession, here's a look at the mysterious figures that make up the North Korean leader's family tree.
