Kim Dong-yub, a former South Korean Navy officer who teaches at Kyungnam University in Seoul, said North Korea may have tested a solid fuel rocket engine, which could allow North Korea to field ICBMs that are easier to hide and faster to deploy.

At the White House's request, Trump and South Korean President Moon Jae-in had a 30-minute phone call to discuss developments related to North Korea, and the two leaders committed to continuing close communication.
Satellite imagery taken on December 5 showed a large container box at the site that was "a decent indicator of an impending engine test", Jeffrey Lewis of the US-based Middlebury Institute of International Studies had said ahead of Pyongyang's statement.
Nuclear talks have been stalled since the summit between Kim and U.S. President Donald Trump in February broke down as they remained far apart over how to match Pyongyang's denuclearization steps with Washington's sanctions relief and other concessions.
