A classified report cited by Germany's Die Welt claims Iranian authorities have prepared contingency plans for a possible mass-casualty scenario during the funeral ceremonies of slain former Supreme Leader Ali Khamenei. The report alleges officials projected between 1,500 and 3,000 potential deaths due to massive crowds and extreme heat, though these claims have not been independently verified. With hundreds of thousands of security personnel deployed and unprecedented security measures in place, what is Tehran preparing for? Is this routine disaster planning, or does it reflect deeper fears surrounding one of Iran's largest state funerals? This report examines the claims, the extraordinary security arrangements, and what they could mean.
