NATO slams Putin rhetoric on nuclear weapons in Belarus

NATO castigated Vladimir Putin over his nuclear rhetoric a day after the Russian president said he planned to station tactical nuclear weapons in Belarus, escalating a standoff with the West.

The plan is one of Russia's clearest nuclear signals since the start of its invasion of Ukraine 13 months ago, and Ukraine called for a meeting of the U.N. Security Council in response.

"Russia's nuclear rhetoric is dangerous and irresponsible," NATO spokeswoman Oana Lungescu said on Sunday.

"NATO is vigilant and we are closely monitoring the situation. We have not seen any changes in Russia's nuclear posture that would lead us to adjust our own."

In his comments on Saturday, Putin likened the move to the U.S. stationing its weapons in Europe, while insisting that Russia would not violate its nuclear non-proliferation promises.

While Washington, the world's other nuclear superpower, played down concerns about Putin's announcement, NATO said the Russian president's non-proliferation pledge and his description of U.S. weapons deployment overseas were way off the mark.

"Russia's reference to NATO's nuclear sharing is totally misleading. NATO allies act with full respect of their international commitments," Lungescu said in a statement. "Russia has consistently broken its arms control commitments."

A top security adviser to Ukrainian President Volodymyr Zelenskiy, Oleksiy Danilov, said Russia's plan would destabilise Belarus, which he said had been taken hostage by Moscow.

Lithuania said on Sunday it would call for new sanctions against Moscow and Minsk in response to Russia's plan.

Lithuania will ask for the additional sanctions to be included in a package of penalties being discussed in Brussels, the foreign ministry's spokesperson said.

Experts said Russia's move was significant since it had until now been proud that unlike the United States, it did not deploy nuclear weapons outside its borders. It may be the first time since the mid-1990s that it has done so.

Mykhailo Podolyak, another senior Zelenskiy adviser, on Sunday scoffed at Putin's plan on Twitter.

"He admits that he is afraid of losing & all he can do is scare with tactics," Podolyak tweeted.

Tactical nuclear weapons refer to those used for specific gains on a battlefield rather than those with the capacity to wipe out cities. It is unclear how many such weapons Russia has, given it is an area still shrouded in Cold War secrecy.

Ukraine called for a meeting of the U.N. Security Council, and it asked the international community to "take decisive measures" to prevent Russia's use of nuclear weapons.

The European Union also condemned Russia's move, with its foreign policy chief Josep Borrell urging Belarus not to host the weapons and threatening further sanctions.

Analysts at the Washington-based Institute for the Study of War said the risk of escalation to nuclear war "remains extremely low."

Putin said Belarusian President Alexander Lukashenko had long requested the deployment. Lukashenko has not publicly addressed the comments.

While the Belarusian army has not formally fought in Ukraine, Minsk and Moscow have close military ties. Minsk allowed Moscow to use Belarusian territory to send troops into Ukraine last year.

Putin on Sunday also asserted that Western powers are building a new "axis" similar to the partnership between Germany and Japan during World War Two.

He has often portrayed the war as Moscow fighting a Ukraine in the grip of supposed Nazis, abetted by Western powers menacing Russia.

Ukraine - which was part of the Soviet Union and itself suffered devastation at the hands of Hitler's forces - rejects those parallels as spurious pretexts for a war of conquest.

On the battlefield, Russian forces hit military targets in Kharkiv, Donetsk, Zaporizhzhia and Kherson regions, causing significant Ukrainian casualties, Russia's defence ministry said on Sunday.

The front lines remain unchanged and Bakhmut continues to be the hottest area on the front, with the fiercest fighting to the north of the city and in the city centre itself, according to Ukrainian military analyst Oleh Zhdanov.

Ukrainian presidential chief of staff Andriy Yermak said Russian forces had destroyed two apartment buildings in a missile strike on the eastern city of Avdiivka in the Donetsk region. He said there were no casualties.

Reuters could not verify the battlefield reports.
