Iranian police detained approximately 21,000 suspects during the 12-day air conflict with Israel in June, according to multiple reports citing Iranian state media and law enforcement officials. The arrests were part of a broad security crackdown amid fears of infiltration by Israeli intelligence. Iranian authorities conducted intensified street checks and relied on public tip-offs, receiving around seven million civilian reports during the conflict. Those detained included alleged spies, individuals filming without permission, and over 2,700 Afghan nationals. Iran's Minister of Security stated that despite the hostile aggression, the country remained in complete peace during the war. Additionally, Israeli forces reportedly attacked Evin prison in Tehran on June 23, resulting in civilian casualties, including prisoners, their families, and staff.
