Britain's Queen Elizabeth II faced a potential assassination threat 40 years ago before a trip to the United States, according to newly released documents from the Federal Bureau of Investigation.
A 103-page document was posted on the FBI's website on Tuesday. The files cover preparations for several trips the late queen made to the US, including an official tour of the West Coast with her husband, Prince Philip, in 1983.
A document details information gathered about a month before that visit by San Francisco police about a call from "a man who claimed his daughter had been killed in Northern Ireland by a rubber bullet."
The document continues: "This man also claimed that he would try to harm Queen Elizabeth and would do so either by throwing an object from the Golden Gate Bridge onto the Royal Yacht Britannia when she sailed under, or by trying to kill Queen Elizabeth when she visit Yosemite National Park.”
The files illustrate the FBI's hypervigilance against possible threats to the British monarch, in cooperation with the US Secret Service, writes CNN.
