The first lady had disappeared for an extended period last year, raising speculation that she could be pregnant.

According to previous intelligence reports from Seoul’s spy agency, Ri married Kim in 2009 and gave birth to their first child the following year, with their second born in 2013.

Kim is the third generation of his dynasty to rule North Korea, but little has been revealed about the country’s first family.
