I haven’t seen anything this detailed about what appears to have been extensive collaboration between North Korea and Syria on some kind of a nuclear project. Jim Hoagland slips the following into his Sunday Washington Post column:

[H]ighly classified U.S. intelligence reports say that the Israelis destroyed a nuclear-related facility and caused North Korean casualties at the site, which may have been intended to produce plutonium, according to a senior official with access to those reports. The Israelis have provided the United States with photographs, physical material and soil samples from the site — taken both before and after the raid — according to two independent sources.
