Iran threatens strikes on US bases following reports of military planning
Tehran warned that American military installations and regional allies will face retaliatory attacks if Washington resumes combat operations agreed to be paused under a June ceasefire.
Threat of base strikes
Iran's military command announced on Sunday, 20 September 2026, that it received intelligence indicating the United States is preparing to resume combat operations against Iranian territory. According to the official communique distributed by the Iranian news agency Tasnim, the decision to restart hostilities was finalized during a multilateral meeting involving American representatives and regional governments. Iranian officials stated that the coordination session took place within an unnamed European country. The armed forces command did not name the specific states involved in the discussions, nor did it describe the tactical details or scope of the planned military measures.
The Iranian military leadership warned that any new offensive move by Washington would immediately trigger unrestricted retaliatory strikes against American assets across the region.
If the United States makes a mistake against the Islamic Republic of Iran, all its bases and interests in the region, without any restrictions, will become targets of continuous, effective and painful attacks.
Warnings to regional host nations
The Iranian armed forces extended their warning to all Middle Eastern governments that provide logistical or operational support to the United States. The military leadership stated that any country assisting an American military initiative will be categorized by Tehran as a direct combatant and an active party to the conflict. According to the communique, regional nations that support an American attack will forfeit any expectation of restraint from Iranian armed forces during retaliatory operations. This warning applies to Persian Gulf states where United States military bases, command centers, and allied personnel are stationed. Tehran has previously treated host installations as direct extensions of American military force.
Background of the military conflict
The exchange of warnings reflects the continuation of a months-long conflict between the United States and Iran that began earlier in the year. Full-scale hostilities commenced on 28 February 2026, initiated by joint American and Israeli military strikes against targets located in Iran. In response to those initial attacks, Tehran launched retaliatory strikes against Israeli territory, American assets, and Persian Gulf states hosting United States military facilities. Washington and Tehran reached an agreement on a temporary ceasefire in June 2026 to pause active fighting, but that deal did not establish a permanent peace or conclude the war. The underlying military dispute has remained unresolved across the Persian Gulf region.

The advisory noted that travelers should prepare for potential travel disruptions stemming from ongoing attacks launched by Iran-backed Houthi rebels against Saudi Arabia.
