 According to Ahmad Hamzeh, Hezbollah's counterintelligence service is divided into Amn al-Muddad, responsible for "external" or "encounter" security; and Amn al-Hizb, which protects the organization's integrity and its leaders. According to Wege, Amn al-Muddad "may have received specialized intelligence training in Iran and possibly North Korea". The organization also includes a military security component, as well as an External Security Organization (al-Amn al-Khariji or Unit 910) that operates covertly outside Lebanon.
