BERLIN (Reuters) - A major cyber attack could trigger a collective response by NATO, NATO Secretary General Jens Stoltenberg said in an interview published by Germany's Bild newspaper on Thursday.

"A severe cyber attack may be classified as a case for the alliance. Then NATO can and must react," the newspaper quoted Stoltenberg as saying. "How, that will depend on the severity of the attack."
