**Deck**: Iran’s joint military command says it will answer any aggression with sustained attacks on U.S. bases and interests in the region, and has warned neighboring states not to let their territory be used in strikes against Iran.

Iran’s joint military command has issued a sweeping warning that it will launch sustained retaliatory attacks against U.S. bases and interests in the region if it comes under military assault, and cautioned neighboring countries against allowing their territory to be used for any such strike.

The Khatam al‑Anbiya headquarters, which coordinates Iran’s armed forces, said Iran’s response to aggression would be without limitations. Tehran also warned regional governments not to allow the United States or others to use their soil to attack Iran, effectively putting existing basing arrangements and access for foreign forces in the spotlight.

That message links any potential U.S. action directly to the choices of nearby states. By telling neighbors not to host or support attacks, Iran is signaling that bases, infrastructure and territory involved in a strike could themselves become targets in a broader confrontation.

For U.S. forces deployed across the Middle East, the statement raises the risk profile around existing installations. Bases, ports and airfields already face threats from missiles and drones; Iran’s talk of unrestricted retaliation suggests it would feel free to range widely across those categories if it judged that Iranian territory had been hit.

The warning comes against a backdrop of regional tension that includes the war in Gaza and ongoing Houthi attacks on targets linked to the United States and its partners. Iran’s statement adds another potential trigger point in a region where miscalculation by states or armed groups could quickly widen into a larger clash.

Global markets and governments will be watching for signs that words are translating into preparations on the ground. Indicators include any visible changes in U.S. or allied deployments near Iran, shifts in the tempo of attacks by Iran‑aligned groups, and Iranian missile or naval drills near key regional chokepoints. A serious incident involving U.S. bases or neighboring states’ territory would be the clearest sign that this latest warning is moving beyond rhetoric.
