On the 30th, the Spanish government decided to close its airspace to aircraft involved in US and Israeli military actions against Iran.
On the 30th, Spain's El País and EFE quoted sources as saying that the Spanish government had decided that day to close its airspace to planes taking part in military operations against Iran—including prohibiting relevant US military aircraft deployed in other European countries from flying over Spanish airspace. At the same time, Spain will not allow the US to use its Rota and Morón de la Frontera military bases. This measure targets only military aircraft, not commercial flights.
Spain's First Deputy Prime Minister and Minister of Economy, Trade and Business, María Jesús Montero, stated in an interview with Spanish media that this measure is part of the government's established position, namely, not participating in or supporting this "unilaterally launched and internationally unlawful war."
Spanish Prime Minister Pedro Sánchez has previously opposed US and Israeli military action against Iran on multiple occasions, stating that it violates international law and declaring that Spain rejects allowing the US to use military bases on its territory to carry out military operations against Iran.
