Russia warns NATO of a possible nuclear response if Kaliningrad is cut off

Russia has warned NATO that it would not hesitate to use nuclear weapons to defend Kaliningrad should any members of the military bloc try to cut off its western exclave from the rest of the country.

The warning sent to NATO echoed statements issued by several Russian embassies in Europe this week which said that Moscow has "information that NATO is preparing (an) air and naval blockade of Kaliningrad and Kaliningrad region."
