A security siren sounded at FRAF Feltwell, used by the US Air Force, amid reports of unidentified drones in the area, the Daily Mail reported, citing eyewitnesses. A woman interviewed by the newspaper, who lives near the base, said that at around 5:30 a.m. local time (as GMT) on November 13, she heard "war sirens", which lasted for five minutes. "I thought maybe it was a drill. We then heard an American male voice over the speakers telling people to stay home and shelter," the woman said. The Flatwell base is located in Norfolk in eastern England, about 10 km (6.2 miles) from the Lakenheath base.
