German minister says participant dialed into military call via non-secure line

Germany's Defence Minister Boris Pistorius said on Tuesday one of the participants on the military call on Ukraine intercepted by Russia had dialed in via a non-secure line and disciplinary measures were being looked into.

Russia had likely intercepted the military call via widespread surveillance, not a spy or targeted surveillance, Pistorius said. The use of WebEx for the call was authorised.

Germany would take technical and organizational measures to ensure such an incident would not happen again, he said.
