The Bahrain Defence Force says its air defence systems thwart several Iranian ‘aerial attacks’. Iran’s Islamic Revolutionary Guard Corps (IRGC) says it has launched six drones at a US air defence radar system at Bahrain’s Riffa Air Base in response to what it describes as hostile US actions. Sirens sounded in Bahrain on Sunday as its Ministry of Interior urged residents to “remain calm” and “proceed to the nearest safe location”.
