The US military declared on Saturday it had taken out an Iranian bunker housing weapons threatening oil and gas shipments in the Strait of Hormuz.The US statement appeared designed to calm the concerns of energy markets and of Washington’s sceptical international allies.Admiral Brad Cooper, head of US Central Command, said US war planes had dropped 5,000-pound bombs on an underground facility on Iran’s coast that was storing anti-ship cruise missiles, mobile launchers and other equipment. “We not only took out the facility, but also destroyed intelligence support sites and missile radar relays that were used to monitor ship movements,” Cooper said in a video statement, revealing details of a strike first announced Tuesday.
