A Washington think tank says it has identified a military base close to North Korea's border with China that is likely intended for stationing of intercontinental ballistic missiles.

The Center for Strategic and International Studies based its report on Jan. 21 satellite images of the base at Hoejung-ni, in North Korea's Chagang province about 25 km (16 miles) from the border with China and 280 km (175 miles) northeast of Pyongyang.

"The Hoejung-ni missile operating base will, according to informed sources, likely house a regiment-sized unit equipped with intercontinental ballistic missiles," the report said.
