The White House warned Wednesday that Russia could use chemical weapons in Ukraine or manufacture a "false flag" operation that uses them.
White House press secretary Jen Psaki, slamming what she called false claims from Russia that the US is developing chemical weapons in Ukraine, tweeted:
"Now that Russia has made these false claims, and China has seemingly endorsed this propaganda, we should all be on the lookout for Russia to possibly use chemical or biological weapons in Ukraine, or to create a false flag operation using them. It’s a clear pattern.”
Psaki also noted Russia’s “long and well-documented track record of using chemical weapons” as well as its pattern of “accusing the West of the very violations that Russia itself is perpetrating.”
Secretary of State Antony Blinken warned earlier this year of the possibility of Russia carrying out a fake or real chemical weapons attack as a manufactured pretext for an invasion into Ukraine. But his comments came before Russia’s full invasion began.
