A major security dragnet has unfolded in Iran during one of the most high-profile moments in its modern history. As millions gathered to bid farewell to the late Supreme Leader Ayatollah Ali Khamenei, Iran’s Ministry of Intelligence announced it had successfully dismantled four organized terrorist cells operating in the country's southeast. Iranian authorities revealed the groups were directly linked to U.S. and Israeli intelligence networks, and confirmed all members have been captured. While officials have not explicitly stated if the cells were targeting the funeral itself, the timing has placed capital security forces on absolute high alert.
