Russia vs. Ukraine

Russian forces have been accused of using widely banned and dangerous weapons known as vacuum bombs that “obliterate” their victims. Russia was accused of using vacuum bombs, or thermobaric weapons, to attack a preschool in northeastern Ukraine while civilians took shelter inside. White House press secretary Jen Psaki said she had seen reports but did not have confirmation that Russia had used these weapons. Psaki added that if it’s true, “it would potentially be a war crime.” The way it works is the weapon is fired or dropped, and the first explosive charge spreads the fuel in a cloud that sucks up oxygen and then flows “around objects and into structures.” As the fuel cloud spreads, the second charge detonates. The explosion creates a blast wave that is most destructive in enclosed spaces, buildings, and even foxholes. A CIA study said the weapons are “prone to indiscriminate use,” and people closest to the explosion are “obliterated.”
