Russia says a U.S. plan to base naval missile interceptors on Spain's coast is "unacceptable," reiterating its worries over the expansion of NATO's anti-ballistic defense system.
Russia's Foreign Ministry said Thursday that a deal between Washington and Madrid to base Aegis Cruisers northwest of Gibraltar "can't but cause concern."
It says the warships' deployment brings about a "significant build-up of U.S. anti-missile capabilities in Europe."
Russia has long criticized U.S. plans for a system that would protect all of NATO's 28 member states against a potential missile attack from Iran.
Moscow says the plans threaten its own nuclear missiles or undermine their deterrence capability. It wants to jointly run the system, while NATO is offering more limited cooperation.
