The United States has accused Russia of using chemical weapons in Ukraine, following a new set of sanctions against the country. The new sanctions come after Ukrainian military leadership first accused Russia in February of using the gas in more than 800 attacks over the course of the war. Moscow denied the allegations at the time, countering that Ukrainian forces are the ones that used banned chemical weapons. Russia violated the Chemical and Biological Weapons Control and Warfare Elimination Act by using the chemical weapon chloropicrin against Ukrainian troops. What is your take on the accusations ?
