  • Russia has asked Iran to provide the Russian Air Force with access to the IRIAF's 3rd Tactical Fighter Base in Hamedan to deploy heavy bombers and tankers, and to use it as a refueling base for fighter jets deployed over Syria
  • Earlier in August 2016, the RuAF was permitted to deploy 8 Su-34 fighters and 4 Tu-22M3 bombers Hamedan, but after the Russians deliberately leaked pictures of their bombers in the base, Iran forced them to leave
  • It is possible that Iran will refuse Russia access to Hamedan, but may offer the 5th Tactical Fighter Base at Omidiyeh again
  • The motivation behind Russia's request is concern that Russian aircraft may need to evacuate Hmeimim Air Base in the event of US-led airstrikes on Syria
  • This information comes from a "valid" source in the IRIAF, according to Taghvaee
