Iran Warns Bulgaria Against Allowing US Military Tanker Aircraft to Operate From Its Bases

BLUFSofia's parliamentary recess and Radev's recent expulsion of US aircraft make approval of the Bezmer basing request before late August unlikely, leaving Tehran's legal threats unforced.

Iranian Foreign Ministry spokesman Esmail Baghaei on Tuesday warned Bulgaria against granting a US request to station up to eight Air Force tanker aircraft at Bezmer Air Base, saying cooperation would make Sofia complicit in "aggression and war crimes" 12. Bulgarian Prime Minister Rumen Radev said parliament is expected to vote on the request, which the US Embassy in Sofia submitted citing a 2006 defense cooperation agreement, after Radev separately ordered US aircraft out of a Sofia airport over a visa dispute 3. Baghaei cited UN General Assembly Resolution 3314 in arguing that Bulgarian territory used to facilitate US operations against Iran could itself constitute an act of aggression under international law 2. Bulgarian Deputy Foreign Minister Marin Raykov said in April, following an earlier Iranian diplomatic protest over tanker aircraft at Sofia Airport, that no combat aircraft were flying over Bulgaria and no strike aircraft were being refueled on Bulgarian soil 4.

Analysis
Bulgaria's parliament, not Tehran's protest, controls whether Bezmer Air Base becomes an active refueling node for US operations against Iran, and Sofia's vote timeline remains unscheduled after Radev's prior expulsion of US aircraft over the visa dispute complicates the calculus. Baghaei's invocation of UN Resolution 3314 signals Tehran intends to frame any Bulgarian approval as a legal predicate for retaliation against Bulgarian territory or interests, not merely rhetorical pressure. Raykov's earlier insistence that no strike aircraft are being refueled from Bulgarian soil suggests Sofia will likely draw a distinction between refueling support and direct combat participation to manage the exposure.
