NEW YORK, October 12. /TASS/. The US administration was engaged in discussions on possible response to Russia’s hypothetical use of a tactical nuclear weapon in Ukraine, US President Joe Biden told CNN in an interview.

"There’s been discussions of that, but I’m not going to get into that. It would be irresponsible of me to talk about what we would or wouldn’t do," Biden was quoted as saying.

Joe Biden told in an interview he does not expect Russian leader Vladimir Putin to use tactical nuclear weapons in the Ukrainian conflict.

"I don’t think he will," Biden said when asked about the possibility of the use of a tactical nuclear weapon. "I think it’s irresponsible for him to talk about it."

In his opinion, this scenario could lead to "just a horrible outcome.".

Biden said he has no plans of meeting with his Russian counterpart Vladimir Putin on the sidelines of the G20 summit in Indonesia, but it depends on the subject that the Russian leader would like to discuss with him.

"It would depend on specifically what he wanted to talk about," Biden told.

Among the issues that he would like to discuss with Putin, the US president named the release of jailed US basketball player Brittney Griner.

Biden once again reiterated that he was not planning to engage in any kind of talks on Ukraine without the participation of the Kiev government.
