Bahrain confirms alarm as Iran claims attacks on Gulf bases Bahrain's interior ministry confirmed that warning sirens sounded in the country after reports of an explosion amid claims of a drone attack targeting Sheikh Isa Air Base. Earlier, Iran's IRNA and Tasnim news agencies published a statement attributed to the Islamic Revolutionary Guard Corps (IRGC), which claimed responsibility for missile and drone attacks on the US Ali Al Salem Air Base in Kuwait and the US Fifth Fleet headquarters in Bahrain. The IRGC said the attacks were carried out in response to recent US strikes on five coastal sites in Iran.
