Belarus announced on Monday the start of training exercises involving Russian nuclear weapons, drawing wide condemnation from neighboring Ukraine.

In 2023, one year after Russia's full-scale invasion of Ukraine, Belarusian leader Alexander Lukashenko agreed to host Russian tactical nuclear missiles.

Russian President Vladimir Putin has stressed Moscow's control over the missiles' use.

In 2024, the Kremlin released a revised nuclear doctrine that placed Belarus under the Russian nuclear umbrella.
