Activists report that Iran's crackdown on nationwide protests has resulted in at least 6,126 deaths and over 41,800 arrests. The figures, compiled by a US-based human rights group, include protesters, government-affiliated forces, children, and bystanders. Iran's government disputes the numbers, claiming a much lower death toll and labeling many victims as 'terrorists.' The reported toll is the highest seen in Iran in decades, evoking memories of the country's 1979 revolution.
