(Reuters) -The United Nations on Friday said it had no evidence Ukraine had a biological weapons program while Washington and its allies accused Russia of spreading the unproven claim as a possible prelude to launching its own biological or chemical attacks.
Russia called the meeting of the 15-member U.N. Security Council to reassert through its envoy Vassily Nebenzia, without providing evidence, that Ukraine ran biological weapons laboratories with U.S. Defense Department support.
Member countries called the claim “a lie” and “utter nonsense” and used the session to accuse Russia of deliberately targeting and killing hundreds of civilians in Ukraine, assertions that Russia denies in a 15-day offensive it calls “a special military operation.”
Izumi Nakamitsu, the U.N. High Representative for Disarmament Affairs, told the council the United Nations is “not aware” of any biological weapons program in Ukraine, which joined an international ban on such arms, as has Russia and the United States along with 180 other countries.
Under a 2005 agreement, the Pentagon has assisted several Ukrainian public health laboratories with improving the security of dangerous pathogens and technology used to research. Those efforts have been supported by other countries and the World Health Organization.
The WHO told Reuters on Thursday that it had advised Ukraine to destroy high-threat pathogens housed in its public health laboratories to prevent “any potential spills” that would spread disease among the population.
The U.S. envoy to the United Nations, Linda Thomas-Greenfield, said Washington was “deeply concerned” that Russia called the session as a “false flag effort” to lay the groundwork for its own use of biological or chemical weapons in Ukraine.
Although she provided no evidence of an imminent Russian threat during the meeting, she said: “Russia has a track record of falsely accusing other countries of the very violations that Russia itself is perpetrating.”
She added: “We have serious concerns that Russia may be planning to use chemical or biological agents against the Ukrainian people.
“The intent behind these lies seems clear, and it is deeply troubling,” she said. “We believe Russia could use chemical or biological agents for assassinations, as part of a staged or false flag incident, or to support tactical military operations.”
RUSSIA CITES U.S. 2003 IRAQ ASSERTION
Responding to Thomas-Greenfield’s statement, Nebenzia recalled then-U.S. Secretary of State Colin Powell’s 2003 Security Council testimony when he presented what Washington claimed was proof that Iraq was hiding banned weapons of mass destruction programs.
The United States used the assertion, which turned out to be false, to justify its 2003 U.S. invasion of Iraq.
Answering the Russian envoy, Thomas-Greenfield said: “I know that you expect me to respond but we’re not going to give any more airtime to the lies that you’re hearing today.”
U.S. allies echoed Thomas-Greenfield’s concerns that Russian President Vladimir Putin’s government was spreading the claim of a U.S.-backed bioweapons program in Ukraine to prepare its own chemical or biological attacks in Ukraine.
“The council should not be served with fantasies or starry-eyed stories, but with proof independently verified and collaborated,” said Ferit Hoxha, the ambassador of NATO member Albania.
“We should therefore be very worried that in spreading such disinformation, a crescendo of allegations about weapons of mass destruction could serve as yet another pretext for Russia to prepare the ground and use chemical or biological weapons during its ongoing invasion of Ukraine,” he said.
French Ambassador Nicholas de Riviere noted, as did several other envoys, that Russia allegedly used a nerve agent in failed attempts to kill jailed opposition leader Alexei Navalny and a former Russian intelligence officer, Sergei Skripal, who defected to Britain, and his daughter.
Russia denies these allegations.
Speaking to reporters earlier on Friday, U.S. President Joe Biden warned Russia that it would pay a “severe price” if its military should use chemical weapons against Ukraine.

A biological weapons program refers to the development and stockpiling of pathogens or toxins for use in warfare or terrorism, which is prohibited under international law.
An international financial institution is an organization that provides financial and technical assistance to countries for development projects, often with a focus on economic stability and growth.
Chemical weapons are toxic chemicals used to harm or kill people, animals, or plants, and their use is restricted under various international treaties.
