NATO does not have any indication that drone debris found on Romanian territory was caused by an intentional attack launched by Moscow against Romania, the alliance's chief said on Thursday.

"We don't have any information indicating an intentional attack by Russia, and we are awaiting the outcome of the ongoing investigation," NATO Secretary-General Jens Stoltenberg told EU lawmakers. (Reporting by Sabine Siebold and Marine Strauss; Editing by Alison Williams)
