Russian President Vladimir Putin said on Friday that his deployment of tactical nuclear weapons to Belarus, something he confirmed for the first time had already happened, was a reminder to the West that it could not inflict a strategic defeat on Russia.

Speaking at Russia's flagship economic forum in St. Petersburg, Putin said Russian tactical nuclear warheads had already been delivered to close ally Belarus, but stressed he saw no need for Moscow to resort to the weapons for now.

"As you know we were negotiating with our ally, (Belarusian President (Alexander) Lukashenko, that we would move a part of these tactical nuclear weapons to the territory of Belarus — this has happened," said Putin.
