US President Joe Biden on Tuesday blasted Russian President Vladimir Putin's stated plan to deploy nuclear weapons in neighboring Belarus, branding it "dangerous" talk.
"This is dangerous kind of talk and it's worrisome," Biden told reporters at the White House.
Washington has denounced the plan, which follows more than a year of Moscow's attempt to conquer pro-Western Ukraine -- a neighbor of both Russia and Belarus.
However, US officials say they have seen no sign of Russia actually moving nuclear weaponry.
"They haven't done that yet," Biden said.
