The 38North website reported yesterday (29 January) that analysis of satellite imagery of North Korea's Sohae Satellite Launching Station suggested it was being prepared for tests involving larger launch vehicles.
On the same day, US director of national intelligence James Clapper stated in a written testimony to the Senate Intelligence Committee that North Korea had expanded the size of the Yongbyon nuclear complex and restarted the plutonium reactor at the site.
Taken together, these reports add weight to the assessment that North Korea is continuing work on a nuclear weapons programme - specifically a miniaturised nuclear warhead capable of being deployed via a missile - although it remains unlikely that it has developed a working nuclear weapons capability.
