The warning responded to British media reports.


Update: Russia has also warned NATO in a diplomatic document seen by Reuters that it is ready to use “the entire arsenal of forces and capabilities,” including nuclear weapons, if the alliance tries to isolate the Kaliningrad region. The document refers to possible strikes on decision-making centers in alliance states “right from the outset.” NATO’s written response said the alliance is defensive and obliged to counter threats to its members from all directions.
