White House warns Russia may use chemical weapons in Ukraine

The US on Wednesday publicly warned that Russia might seek to use chemical or biological weapons in Ukraine as the White House rejected Russian claims of illegal chemical weapons development in the country it has invaded.

This week, Russian Foreign Ministry spokeswoman Maria Zakharova — without evidence — accused Ukraine of running chemical and biological weapons labs with U.S. support. White House press secretary Jen Psaki called Russia’s claim “preposterous” and said it could be part of an attempt by Russia to lay the groundwork for its own use of such weapons of mass destruction against Ukraine.

“This is all an obvious ploy by Russia to try to justify its further premeditated, unprovoked, and unjustified attack on Ukraine,” Psaki tweeted Wednesday. “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.”

The U.S. for months has warned about Russian “false flag” operations to create a pretext for the invasion. Wednesday’s warning suggested Russia might seek to create a pretense for further escalating the two-week old conflict that has seen the Russian offensive slowed by stronger-than-expected Ukrainian defenders, but not stopped.

Dmitry Chumakov, a Russian deputy U.N. ambassador, repeated the accusation Wednesday, urging Western media to cover “the news about secret biological laboratories in Ukraine.”
