North Korean leader Kim Jong-il has died of a heart attack at the age of 69, state media has announced.
Millions of North Koreans had been "engulfed in indescribable sadness", the KCNA news agency said. People were seen weeping in the capital Pyongyang.
His son Kim Jong-un was described by KCNA as the "great successor" who North Koreans should unite behind.
We'll see soon enough whether the military will want to continue with a figurehead in charge or if they want to come out of the shadows. The "Great Successor" will live only so long as the generals allow it.
