Mohammad-Javad Larijani, a former top advisor to Supreme Leader Ali Khamenei, described the attack that killed Hassan Nasrallah as the result of a "serious informational and security breach" within the Tehran-supported regional militia, referred to as Resistance. He said that the "Zionist regime managed to exploit vulnerabilities, causing significant damage," whether through "pagers or other gaps," and stressed that "even the recent bombing was the result of infiltration."
