Diplomatic Agents, adopted on 14 December 1973, the Convention for the Suppression of Unlawful Acts against the
Safety of Civil Aviation, signed on 23 September 1971, the Convention for the Suppression of Unlawful Seizure of
Aircraft, signed on 16 December 1970, and other relevant conventions,

Protected Persons, including Diplomatic Agents, the Convention for the Suppression of Unlawful Acts against the
Safety of Civil Aviation, the Convention for the Suppression of Unlawful Seizure of Aircraft and other relevant
conventions;
