Head of the Arab Gulf Center for Iranian Studies Dr. Mohammed bin Saqr al-Salami said that Iranian authorities' continued delay of the investigation of the incident of the storming of the Saudi embassy in Tehran and its consulate in Mashhad their practice of blackmail to obtain diplomatic privileges reflects the behavior of the Iranian government and its non-respect for international covenants, conventions and laws and its lack of seriousness in revealing the identity of the perpetrators involved in this act, which is a clear and explicit violation of the Vienna Convention for the Protection of Diplomatic Missions. He detailed Iran's long record in violation of diplomatic missions over the past four decades from the attack on the US Embassy in 1979, then on Saudi Arabia in 1987, then the British, French and Danish between 2010 and 2012 and lastly the Saudi Embassy again in 2016, in addition to attacks on many diplomats and targeting them for assassination inside and outside Iran. Dr. Al-Salami said: "These testimonies reflect the lack of respect by the Iranian regime for all international treaties and conventions concerning the protection of diplomatic missions and their employees and negligence in prosecuting the perpetrators through the presence of representatives of the affected state to ensure knowledge of the circumstances of the case and those behind it. He pointed out that the procrastination of the Iranian regime in investigating the incident of the storming of the Embassy of the Kingdom of Saudi Arabia in Tehran and its general consulate in Mashhad strengthens the analysis of the involvement of the Revolutionary Guards and the Basij forces in this attack, especially in the presence of many indicators and pictures that show prominent figures in the forces Basij in front of the embassy at the time of the incident, and the security men standing idly by and without the task of protecting the embassy and the consulate.
