Iranian forces have reportedly considered contingency plans to strike US military assets in southeastern Europe, including Bulgaria and Cyprus, if President Donald Trump escalates the conflict, according to people close to Iran’s leadership cited by the Financial Times. The reporting describes this as contingency planning rather than evidence of an imminent attack on European territory.

The outlets also say Iranian planners have examined other options in the Strait of Hormuz, including attacks on subsea fibre-optic cables if hostilities intensify. The Strait of Hormuz remains a central flashpoint, with Iran saying it will restrict the waterway until its demands are met, while the United States continues to apply pressure.

Context for the assessment includes a wider standoff in which diplomatic channels between Washington and Tehran are described as stalled. One report frames the guidance as signaling to both the United States and European countries that host or support US military activity, citing prior Iranian warnings to Bulgaria after it allowed US refuelling aircraft to use its Bezmer air base.
