Iran's Revolutionary Guards Corps (IRGC) has banned all members from using communication devices following attacks on Hezbollah's devices in Lebanon. The IRGC is inspecting all devices, including homemade and imported ones, due to concerns about Israeli infiltration. Iranian security officials have begun a thorough investigation of personnel, targeting mid and high-ranking members of the IRGC. The attacks on Hezbollah's devices killed 39 people and injured over 3,000. Iran's main concern is the protection of its nuclear and missile facilities, and security measures at those sites have significantly increased since last year.
