North Korean state media issued two photos Friday that, either by accident or design, appeared to show plans for striking the US mainland, as well as details of the North's military strength.
The pictures, released by the official Korean Central News Agency (KCNA), both showed leader Kim Jong-Un sitting at a desk in what looked like a dedicated military operations room.
The photos accompanied a KCNA report on an emergency meeting with top army leaders in which Kim ordered strategic rocket units to prepare for a possible strike against US mainland and Pacific bases.
One picture showed Kim amongst four uniformed officers, but the main interest lay in the background.
The left of the picture showed a map with the unambiguous title: "Strategic Forces' US Mainland Striking Plan."
Straight lines on the map -- not all of which was visible -- appeared to show the proposed flight paths of missiles striking targets in the continental United States.
"I don't think this is a mistake," a South Korean defence ministry official told AFP.
"I believe it has been intentionally made public, probably in order to distort facts about the North's military power," the official said.
