In the U.S., the bodyguard who failed to save Kennedy from the bullet has passed away (video).

Secret Service agent Clint Hill, who attempted to save U.S. President John F. Kennedy and First Lady Jacqueline Kennedy in Dallas in 1963, has passed away at the age of 93. This was reported by Daily Mail.

Hill died at his home in Belvedere, California, on Friday, according to his publisher, Gallery Books, a division of Simon & Schuster. The cause of death has not been disclosed.

Hill was forced to retire early in his career as he was haunted by memories of the assassination.

Although few know his name, footage filmed by Abraham Zapruder during the assassination of Kennedy in Dallas on November 22, 1963, shows Hill attempting to save the President and First Lady.

For his actions that day, Hill received commendations from the Secret Service and was promoted, but for decades he blamed himself for John F. Kennedy's death. He felt guilty for not reacting quickly enough and would gladly have given his life to save the President.

"If I had reacted just a little faster… And I could have, I suppose. And I will live with this until my grave," Hill told a tearful Mike Wallace on CBS's "60 Minutes" in 1975, shortly after he retired at the age of 43 on his doctors' advice.

The agent admitted that he only came to terms with what happened in Dallas towards the end of his life.

On the day of Kennedy's assassination, Clint Hill was assigned to protect First Lady Jacqueline Kennedy and was riding on the left running board of the car directly behind the presidential limousine.

Hill later recounted that he reacted upon hearing the shot and seeing the President fall: the bullet struck Kennedy in the head before Hill could reach the limousine.

Zapruder's footage captured Hill leaping from the Secret Service vehicle, grabbing the rear of the limousine, and pulling himself up as the driver accelerated. He urged Mrs. Kennedy, who had climbed onto the trunk, to return to her seat as the limousine pulled away.

Hill later became an agent responsible for White House security and then an assistant director of the Secret Service, retiring due to what he described as deep depression and recurring memories of the assassination.

He worked in the agency's Denver office for about a year before joining an elite group of agents assigned to protect the President of the United States and the First Family.

After retiring, Hill spoke publicly about the assassination only a few times. He later authored several books.

It’s worth noting that U.S. President Donald Trump, upon returning to the White House, ordered the declassification of the last secret files regarding the assassination of John F. Kennedy in Dallas in 1963, to answer the popular question "Who killed Kennedy?" and put an end to speculation on the topic.
