LONDON: A sizable number of US Patriot air defense missiles have been moved from Europe toward the Middle East as Washington diverts resources toward its war on Iran, leaving concerning gaps in Europe’s air defenses against Russia, US defense officials told The Associated Press. The war in Iran, about to enter its fourth week, has seen the US deploy thousands of troops to the region and pushed the Pentagon to seek an additional $200 billion in funding. Iran meanwhile has fired missiles and drones across the Gulf, including at US bases and hotels in vacation hot spots.
