North Korea is using its embassy in Berlin to buy technology for its weapons program, Germany’s intelligence chief Hans-Georg Maassen told German broadcaster ARD.
He added that German authorities believe chunks of Pyongyang's weapons program were "acquired through shadow buyers or shadow markets abroad, which they then bought in Germany."
"If we find such things, we stop it, but we cannot guarantee that this can be prevented in all cases," Massen said, according to a press release cited by CNN of which ARD is an affiliate.
