WASHINGTON (Reuters) -Russia's false accusations that Kyiv has biological and chemical weapons illustrate that Russian President Vladimir Putin is considering using them himself in his war against Ukraine, U.S. President Joe Biden said on Monday, without citing evidence.

Putin's "back is against the wall and now he's talking about new false flags he's setting up including, asserting that we in America have biological as well as chemical weapons in Europe, simply not true," Biden said at a Business Roundtable event.
