Belarusian President Alexander Lukashenko said on Friday that his country had modified their SU-24 warplanes to carry nuclear weapons and stated that Minsk would react immediately if the West caused any problems.
Lukashenko said that the decision to upgrade Belarusian warplanes was made through an agreement with Russian President Vladimir Putin, the Belta news agency reported.
Belarus, a close ally of Russia, does not have its own nuclear weapons.
Lukashenko did not elaborate on how nuclear weapons from Russia could transfer to Belarus. Putin is currently using Belarusian territory to mount his so-called "special military operation" in Ukraine.
Lukashenko spoke about Poland, an active NATO member, as being a potential future threat to Belarus, he also said that he was confident that the Polish military, unlike Warsaw's politicians, understood how Minsk could respond to any "escalation."
He appeared to be issuing a threat to the West in general, and not just Poland specifically, saying: "They (the West) must understand that if they opt for escalation no helicopters or planes will save them."
Referring to the work to upgrade his military's warplanes to be capable of carrying nuclear weapons, Lukashenko said: "Everything was ready.
"It's not a good idea to escalate things with Belarus because that would be an escalation with the Union State (of Russia and Belarus) which has nuclear weapons. If they start to create problems the response will be immediate."
