Iran’s security forces may have used lethal chemical weapons against them. Former British MP Bill Rammell stated that the Iranian authorities might have used toxic chemical substances during the deadliest suppression of protests in the country's modern history, citing a credible report he had reviewed. People believe that some kind of toxic chemical substance was used against the protesters, as a result of which some of the injured died a few days later, Rammell said in an interview with GB News. If confirmed, such actions would be an extreme escalation of the methods used by the Iranian authorities against their own population, the former MP noted. Footage published on social media allegedly showed the use of unconventional means to disperse protesters in the city of Sabzevar in eastern Iran. The footage shows people in protective suits and masks designed for working with dangerous chemicals, located on sand-colored vehicles deployed on the city streets. The video also shows a yellow triangular sign with a dark border, indicating a warning about dangerous materials. In addition, photos obtained by Iran International allegedly captured a sniper on the roof of the Isfahan municipal building, who was targeting demonstrators.
