Government officials believe North Korea is continuing to manufacture missiles in a facility near its capital of Pyongyang.
According to The Washington Post, the officials cited satellite images that purportedly show activity at the Sanumdong military facility. North Korea has already made two of its ICBMs at that plant.
Intelligence officials told the Post that trucks and shipping containers can be seen at the facility. They believe North Korea is building at least one of its Hwasong-15 missiles there.
"We see them going to work, just as before," one official told the Post.
Independent experts came to the same conclusion. Jeffrey Lewis of the James Martin Center for Nonproliferation Studies told the Post the site is "active. We see shipping containers and vehicles coming and going. This is a facility where they build ICBMs and space-launch vehicles."
