IRNA – The Islamic Republic of Iran is a guarantor to regional security, said Head of Foreign Ministry's Institution for Political and International Studies (IPIS) Mohammad-Kazem Sajjadipour on Thursday.

He said Iran, a country with 15 neighbors, links different regions such as Central Asia, the Caucasus, the Indian Sub-Continent and east of Arab world.
