MOSCOW - Russian Deputy Foreign Minister Sergei Ryabkov on Thursday warned that NATO nuclear facilities would become a military target for Russia if they were permanently located on the Polish territory.

"The expansion of the practice of joint NATO nuclear missions - regardless of who becomes that country or those countries that can join those already participating in this practice - is of a purely destabilizing nature. And in fact, threatening," Ryabkov said in an interview with Russia's TASS news agency.

Polish President Andrzej Duda stated that the Polish authorities have repeatedly discussed with the US the possibility of deploying nuclear weapons in Poland within the framework of NATO's nuclear sharing arrangements

He said that the approach of joint nuclear missions by NATO countries near Russian borders exacerbates security threats.

"I'm not even talking about permanent deployment, which is also being hotly discussed by hotheads in Warsaw. Therefore, all those politicians who are now enthusiastically discussing such a scheme in Poland and beyond, for their own reasons, must understand: shifts in this direction will not add to Poland's security, but the corresponding facilities will certainly become a target. They will be at the forefront in our military planning," he stressed.

Ryabkov referred to the ongoing discussion about deploying NATO nuclear facilities in Poland as an "evolving story".

Moscow closely monitors how Warsaw addresses this topic, he said.

Polish President Andrzej Duda, in an interview with the Fakt newspaper on Monday, stated that the Polish authorities have repeatedly discussed with the United States the possibility of deploying nuclear weapons in Poland within the framework of NATO's nuclear sharing arrangements and expressed readiness for it if necessary.
