Putin plans nuclear test on Ukraine's borders 

This is reported by The Times.

The publication notes that the Kremlin signals readiness for a significant escalation of the war in Ukraine.  This is associated with the fact that Russia is losing its positions on the battlefield.

The readiness to use nuclear weapons is also evidenced by the recent information that the train of the secret nuclear division is moving towards the borders of Ukraine.

According to Polish military analyst Konrad Muzyka, a train with military equipment was spotted in the central part of Russia.  It is associated with the 12th Main Directorate of the Russian Ministry of Defense and is "responsible for nuclear munitions, their storage, maintenance and transportation."
