Italy Blocks US Military Aircraft from Sicily Base Over Iran War Operations

2026-03-30 region

Sicily, 1 April 2026
Italy has denied US military aircraft access to the strategic Sigonella air base in Sicily, marking a significant diplomatic rift between NATO allies. Defence Minister Guido Crosetto refused permission after discovering American bombers planned to use the facility for Iran war operations without prior authorisation - learning of the flights only after aircraft were already airborne on 27th March 2026.

Unauthorised Flight Plans Trigger Diplomatic Response

The Italian government’s decision came after discovering that several US bombers were planning to land at Sigonella before flying to the Middle East for operations against Iran [1][2]. Italian Air Force authorities only learned of these plans after the aircraft had already taken off, with no prior notification or consent from the Italian side [7]. A source confirmed to Reuters that Italy refused permission on 27th March 2026 [2], while the Corriere della Sera newspaper first reported the incident on Tuesday, 31st March [1][6]. Defence Minister Guido Crosetto’s refusal was based on preliminary checks that revealed the flights were neither routine nor logistical operations, falling outside the scope of bilateral agreements governing US use of military bases in Italy [6][7].

Treaty Violations and Parliamentary Requirements

Italian officials emphasised that such military operations require prior authorisation and appropriate political consultations under existing treaties [6][7]. Following the outbreak of the US-Israeli war on Iran, Prime Minister Giorgia Meloni and Defence Minister Crosetto had previously stated that the United States could continue using bases in Italy for routine operations under existing agreements, but any activities beyond that scope would require parliamentary approval [6][7]. The government issued a statement explaining that requests to use facilities ‘are examined carefully, on a case-by-case basis’ and insisted there were ‘no critical issues or frictions with international partners’ [2]. Despite the refusal, Rome maintained that ‘relations with the United States, in particular, are solid and based on full and loyal cooperation’ [2].

Growing European Resistance to Iran War Operations

Italy’s decision reflects a broader pattern of European reluctance to support US military operations against Iran. Spain had already closed its airspace to US planes involved in attacks on Iran on 30th March 2026 [2][4], with Spanish Defence Minister Margarita Robles stating that ‘two countries went to war and expected us to join them’ [4]. Spanish government officials had earlier disallowed US jets and refuelling aircraft from using the Rota and Morón bases near Cádiz and Seville to attack Iran at the start of March 2026 [4]. Flight-tracking data showed that more than a dozen US aircraft left the Rota and Morón facilities within days of the start of the war [4]. President Donald Trump has responded aggressively to European resistance, threatening to cut off all trade with Spain and labelling the country ‘terrible’ [4].

Strategic Base Faces Diplomatic Tensions

Sigonella air base, located near Catania in eastern Sicily, serves as a key strategic hub for US operations in the Mediterranean [5]. The facility hosts both an Italian Air Force base and a US Navy base, and is also used by NATO forces [5]. The base’s strategic importance has made Italy’s refusal particularly significant for US Middle East operations. Italian opposition politician Anthony Barbagallo, the Sicilian head of the centre-left Democratic Party, praised the decision, stating that ‘Minister Crosetto’s decision to deny landing permission is a significant and appropriate step that confirms the validity of the concerns we raised’ [2]. Prime Minister Meloni has criticised the war as ‘outside the scope of international law’ and insisted that Italy is not involved in the conflict [4]. According to recent polls, a large majority of Italians oppose the war [5], adding domestic political pressure to the government’s position on military base access.
