The US Federal Bureau of Investigation (FBI) has released documents showing that Queen Elizabeth II faced potential assassination threats during a visit to the US in 1983. This is reported by the BBC.

 FBI files show how the bureau helped ensure the monarch's safety during her visits. According to their data, a threat to kill Elizabeth II came to a police officer in San Francisco. The assassination threat was made on February 4, 1983, about a month before the visit of Queen Elizabeth II and her husband Prince Philip to California.

 According to the file, an officer who frequented an Irish pub in San Francisco alerted federal agents to a call from a man he met at the establishment. He reported that the man said he wanted revenge for his daughter, who "was killed in Northern Ireland by a rubber bullet."

 "He intended to harm Queen Elizabeth, and would do so either by throwing an object from the Golden Gate Bridge onto the Royal Yacht Britannia as she passed under it, or by attempting to kill Queen Elizabeth when she visited Yosemite National Park." - the document says.

 In response to the threat, the FBI planned to "close lanes on the Golden Gate Bridge as the yacht approaches." It is said that it is unclear what measures were taken in Yosemite, but the visit did take place. The bureau has not released any details of the arrests.

 The 102-page cache file was uploaded to Vault, the FBI's intelligence website, on Monday following a Freedom of Information Act request by United States media. As the BBC writes, many of the late queen's state visits to the United States, including a 1983 visit to the West Coast, took place during heightened tensions amid the turmoil in Northern Ireland.

In 1976, the late queen was in New York to celebrate America's 200th anniversary. Documents show the pilot was cited by police for flying a small plane over Battery Park with a sign saying "England Get Out of Ireland". The FBI "remained alert" to what it believed were real potential threats to the late queen, according to the files.

 In addition, on the eve of the late Queen's personal visit to Kentucky in 1989, an internal bureau memorandum stated that "the likelihood of threats to the British Monarchy is ongoing from the Irish Republican Army (IRA)". Police said that "Boston and New York have been asked to remain alert for any threats against Queen Elizabeth II by members of the IRA and to immediately notify Louisville" in Kentucky.

 The late queen, who owned racehorses, was known to visit Kentucky several times during her lifetime, including the Kentucky Derby. During a state visit in 1991, the late Queen was reportedly scheduled to attend a Baltimore Orioles baseball game with President George W. Bush. The FBI warned at the time that "Irish groups were planning to protest at the stadium" and that the Irish group had "reserved a large number of grandstand tickets" for the game.

 On May 23, the annual flower exhibition was held in London's Chelsea district. It was visited by members of the royal family and celebrities. This year, special attention was paid to the favorite flowers of the late Queen Elizabeth II.
