North Korea is observing a three-day period of mourning for Fidel Castro, seen by the North as a rare comrade-in-arms against the common enemy of the United States.

State media reported Monday that the North has ordered flags outside official buildings be flown at half-staff to honor Castro. The iconic Cuban leader died Friday at age 90.

Reports from Pyongyang said North Korean leader Kim Jong Un sent a wreath to the Cuban Embassy and that a delegation of senior North Korean officials has left for Havana to attend Castro's memorial services.

According to a Japanese agency that monitors North Korean media, Castro is the first foreign political figure to be honored in such a manner since Palestinian leader Yasser Arafat, who died in 2004.
