Italy has reportedly refused permission for US military aircraft to land at the Sigonella air base in Sicily while heading toward the Middle East. The decision marks a rare setback for the United States from a NATO ally.

According to the Italian newspaper Corriere della Sera, the move involves “some US bombers" planned for deployment in the region.

Authorisation Rules Trigger Refusal

Naval Air Station Sigonella serves as a key hub for NATO and US operations. However, Italian authorities said the required approval process was not followed.

Under existing agreements, Rome must be formally consulted before any US military activity takes place at bases on Italian soil. Reports suggest that the US did not seek prior clearance or inform Italy’s military leadership, which led to the denial.

So far, Italy’s defence ministry has not released an official public statement on the matter.

Spain Takes Similar Stand

The development comes shortly after Spain also denied access to its airspace and military bases for US operations linked to Iran.

Spanish Defence Minister Margarita Robles said, “the bases are not authorised, and of course neither is the use of Spanish airspace for actions related to the war in Iran."

US Operations Face Logistical Challenges

Spain’s decision has complicated US military planning. Reports by El Pais indicate that American bombers have had to alter their routes and travel plans. Emergency landings remain the only exception.

Sanchez Leads Opposition to War

Spanish Prime Minister Pedro Sanchez has been one of the most vocal Western leaders opposing the conflict, which began after US-Israeli strikes on February 28 and has since escalated across the region.

Tensions Rise Between US and Spain

Sanchez’s position has drawn criticism from the White House. President Donald Trump has warned of possible trade consequences and criticised Spain for not increasing its NATO defence spending to five percent of GDP, as requested by Washington.
