Nuclear risk during the Russian invasion of Ukraine

The Kremlin said Monday that U.S. President Joe Biden's outgoing administration will further inflame tensions by allowing Ukraine to use long-range missiles for strikes inside Russia.

Russian President Vladimir Putin said on Sunday he hoped the West "heard" his warning about the danger of a direct war with NATO if it allowed Ukraine to use long-range weapons against Russia.

Putin made the initial threat in September after Britain and the United States mulled letting Kiev use long-range arms against Russian targets, warning this would put NATO "at war" with Moscow.

The Kremlin said on Thursday that an updated nuclear doctrine that will allow Moscow to use nuclear weapons against non-nuclear states should be seen as a warning to the West.

Russian Foreign Minister Sergey Lavrov issued a stern warning to the United States on Wednesday, cautioning against disregarding Russia's "red lines."
