From the Express [tabloid]:
The US has been given a chilling ‘WW3 by Christmas’ warning by pro-Putin spokesperson Sergey Markov.
Western allies, also including Britain and France, have taken a “big jump” towards a nuclear conflict by giving Ukraine permission to fire Western long-range missiles into Kremlin territory, Markov claims. A regular Putin “mouthpiece”, Markov warned that the shock move by President Joe Biden could mean that Britons could be facing a Christmas in shelters.
