Aircraft carrier strike groups from the US Navy and British Royal Navy have assembled in the North Sea for a colossal two-week NATO exercise.

NATO will not be cowed by Russian threats but keep up its strong support of Kyiv, NATO Secretary-General Mark Rutte said on his first visit to the alliance's Ukraine mission in Wiesbaden, set to take over the coordination of military aid from the U.

"The message (to Russian President Vladimir Putin) is that we will continue, that we will do what's necessary to make sure that he will not get his way, that Ukraine will prevail," Mark Rutte said during a joint interview with Reuters and German radio Hessischer Rundfunk on Oct.

The carrier strike group will conduct operations in the North Sea with allies and partners, the U.S. Navy said.
