Russian officials announced Wednesday that Kim Jong Un will make his first official visit to Russia in May. He will attend a commemorative ceremony in Moscow to mark the 70th anniversary of the Soviet Union's victory in World War II.

South Korea's Yonhap News Agency reported the news, adding that the Kremlin had invited Kim Jong Un, along with 20 other "state leaders," to attend the ceremony.

The Kremlin stated that "North Korea's leader" would attend the event, and while most people took that to mean Kim Jong Un would visit, South Korean officials told the Yonhap News Agency that the phrase could also refer to Kim Yong-nam, the nominal head of state for foreign relations. Meghan DeMaria
