WASHINGTON, March 29. /TASS/. US President Joe Biden has told reporters that, in his opinion, Russia has not yet deployed its tactical nuclear weapons in Belarus, but he is concerned by those plans.

Biden told reporters after returning to Washington from North Carolina that he had not yet familiarized himself with Russia’s official statements on the issue, but expressed concern about the possibility.

"They haven’t done that yet unless something happened while I was on the helicopter," the US president said.

When asked to comment on Russian President Vladimir Putin’s earlier remarks on the issue, Biden said: "This is dangerous kind of talk he uses, and it’s worrisome."

White House National Security Council Strategic Communications Coordinator John Kirby said earlier that his country saw no evidence of Russian nuclear weapons being deployed in Belarus, and will not delve into hypothetical scenarios.

Russian President Vladimir Putin announced on March 25 that, at Minsk’s request, Moscow would deploy its tactical nuclear weapons in Belarus, similar to what the United States has been doing for some time on the territories of its allies. Russia has already handed over the nuclear-capable Iskander missile system to Belarus. According to the Russian leader, the construction of a storage facility for tactical nuclear weapons in Belarus is to be completed on July 1.
