Following Russia’s invasion of Ukraine on February 24, 2022, there have been a number of accusations and concerns regarding chemical and biological weapons. The following is a chronological summary of key events and quotes related to chemical and biological weapons developments during the conflict. The timeline will be updated as necessary.

March 8: During the 99th Executive Council session of the Organization for the Prohibition of Chemical Weapons (OPCW), the Ukrainian delegation condemned Russian misinformation and re-affirmed Ukraine’s compliance with and support for the Chemical Weapons Convention. Ukrainian Amb. Maksym Kononenko made it clear that, should a chemical incident occur in Ukraine, Ukraine will invoke Article X of the Chemical Weapons Convention, which calls for the delivery of “Assistance and Protection Against Chemical Weapons” by other States Parties to the CWC.
Forty-nine nations submitted a joint statement to the OPCW condemning Russia’s disinformation campaign, particularly Russian Defense Minister Shoigu’s December 21 statements (see Dec. 21 in timeline).
March 9: Russian foreign ministry spokesperson Maria Zakharova said that Russia “has documents showing evidence that the US had supported a bioweapons program in Ukraine,” and that “Ukrainian nationalists” were preparing a chemical weapons “provocation” (The Guardian). The State Department and White House categorically denied the claims.
March 9: White House spokeswoman Jen Psaki warned that Russia could “possibly use chemical or biological weapons in Ukraine, or to create a false flag operation using them.”

March 10: Russia submitted a National Document to the OPCW entitled “About the possible chemical provocations in Ukraine” repeating its claim that American “special services” have provided Ukraine chemicals for “various types of provocations” (Document page 13). The document outlined several possible ways a chemical attack could take place.
March 10: Appearing before a Senate Intelligence Committee hearing on worldwide threats to the U.S., CIA Director William Burns stated: “Whether it’s the potential for the use of chemical weapons either as a false flag operation or against the Ukrainians, this is something that all of you know is very much a part of Russia’s playbook. They’ve used those weapons against their own citizens, they’ve at least encouraged their use in Syria and elsewhere, so it’s something we take very seriously.”
March 11: The Russian Mission to the U.N. called for a U.N. Security Council meeting to discuss its accusations that the United States is funding a network of military biological laboratories. The United States Delegate, Amb. Linda Thomas-Greenfield, responded: “There are no Ukrainian biological weapons laboratories supported by the United States – not near Russia’s border or anywhere.” U.N. High Representative for Disarmament Affairs, Izumi Nakamitsu, dismissed the claims, saying “the United Nations is not aware of a biological weapons program” in Ukraine.

Ukraine also stated concern that the “Russian Federation is going to launch a massive chemical attack on the territory of Ukraine, in the capital of Ukraine city of Kyiv and Kyiv region as well as in temporarily occupied Donetsk using tanks with ammonia and central nervous system acting chemicals.”
March 21: An ammonia leak occurred at a Sumykhimprom chemical facility in Sumy, Ukraine. The factory produces fertilizers.

Russia has accused Ukraine of staging a “chemical false flag.”

And he’s – now he’s talking about new false flags he’s setting up, including he’s asserting that, we, in America, have biological as well as chemical weapons in Europe – simply not true. I guarantee you.” He followed this statement with: “They’re also suggesting that Ukraine has biological and chemical weapons in Ukraine. That’s a clear sign he is considering using both of those. He’s already used chemical weapons in the past.”

March 24: In a joint statement, NATO countries promised to “continue to provide assistance in such areas as cybersecurity and protection against threats of a chemical, biological, radiological, and nuclear nature” during a meeting of the NATO Heads of State and Government.

March 25: During a press gaggle, U.S. National Security Advisor Jake Sullivan mentioned that the United States has established a “Tiger Team” of national security experts to “look at a range of contingencies” should Russia use chemical, biological, or nuclear weapons.

April 7: The G7 foreign ministers and the high representative of the European Union issued a joint statement “On Russia’s War of Aggression Against Ukraine.” The statement included the following: “We warn against any threat or use of chemical, biological or nuclear weapons. We recall Russia’s obligations under international treaties of which it is a party, and which protect us all. Any use by Russia of such a weapon would be unacceptable and result in severe consequences. We condemn Russia’s unsubstantiated claims and false allegations against Ukraine, a respected member of the Biological and Toxin Weapons Convention and the Chemical Weapons Convention that is in compliance with its legal obligations under those instruments.”

The document alleged that “Russia retains an undeclared chemical weapons program and has used chemical weapons twice in recent years,” referring to an assassination attempt in the UK in March 2018, and an assassination attempt in Russia in August 2020. No mention of Ukraine was made in the document.
April 20: White House spokesperson Jen Psaki was asked for an update on U.S. assessments of the alleged chemical incident in Mariupol (see April 11). Psaki replied that “there’s no new assessment.” She added that because the U.S. doesn’t have a team on the ground, the situation is “difficult to assess,” but that the U.S. will continue to work on investigating the incident.

April 26: During a press conference at the Rossiya Segodnya information agency, Russian Permanent Representative to the Organization for the Prohibition of Chemical Weapons Alexander Shulgin stated: “When Ukraine joined the chemical convention, it did not declare the presence of chemical weapons on its territory, but I think that, one way or another, the Ukrainians will play this card. I already spoke about encroachments regarding chemical provocations against our country.”
