Spain has restricted access to its airspace for United States military aircraft involved in operations linked to the Iran conflict, in a move that highlights growing tensions between Washington and some European allies.

Spanish officials said the restriction applies specifically to U.S. military flights connected to the escalating conflict, and does not affect civilian air traffic. The measure follows earlier decisions by Madrid to deny the use of Spanish military bases for operations related to the war.

The move reflects Spain’s cautious stance toward the widening conflict, with authorities seeking to avoid direct involvement as tensions between Iran and its adversaries intensify. Officials have emphasized the importance of de-escalation and regional stability.

The decision has also underscored divisions within Western allies, as the United States pushes for broader cooperation while some European countries remain reluctant to support military operations tied to the conflict.

Spain’s restriction signals a broader concern in Europe about the global spillover of the Iran war, with governments increasingly taking steps to distance themselves from direct participation.
