PARIS, Sept. 18 (Xinhua) -- Airbus said Wednesday that it has "self declared" to German authorities of "potential wrongdoings" by several employees, regarding customer documents related to two future German procurement projects.

The European aerospace group said the self-disclosure follows an ongoing internal review and the two future German procurement projects are about communications, intelligence and security business.
