Switzerland has declined requests from the United States to allow military-related flights through its airspace in connection with the ongoing conflict involving Iran, citing its obligations under international neutrality laws.
The Swiss government disclosed on Saturday that two requests tied to the war were rejected after being reviewed under the country’s neutrality policy.
“In total, two requests linked to the war in Iran were refused, while a maintenance flight and two requests for transport aircraft were approved,” the government said in a statement.
According to authorities, the rejected requests involved reconnaissance flights scheduled for March 15.
Explaining the decision, the Swiss government said its neutrality laws prohibit the use of its territory for military activities related to armed conflicts.
“The law of neutrality prohibits overflights by parties to a conflict for military purposes related to that conflict,” the statement said, referencing the war involving the United States, Israel and Iran.

However, the government noted that certain categories of flights are still allowed under international rules.
Flights for humanitarian or medical purposes, including the transport of injured persons, as well as flights not connected to the conflict, remain permitted.
The development comes amid heightened diplomatic tensions among Western allies over access to military facilities and airspace following the escalation of hostilities in the Middle East.
At the start of the war, US President Donald Trump publicly criticised the United Kingdom for initially hesitating to allow American forces to use its bases, and later threatened Spain with trade measures after Madrid declined a similar request.
