Poland has sharply criticized Russian President Vladimir Putin's recently announced deployment of nuclear weapons to Belarus.
"We condemn this intensification of the threat to peace in Europe and the world," a foreign ministry spokesman in Warsaw said on Sunday, according to the PAP agency.
Belarus is a neighbour of Russia as well as Poland and Ukraine, which has been fighting an invasion by Russian troops for more than a year.
Putin had said on state television on Saturday evening that the leaders in Moscow and Minsk had agreed on such a move, which Russia said would not be in violation of the international Treaty on the Non-Proliferation of Nuclear Weapons.
