On 22 November 1963, US President John F. Kennedy was assassinated while travelling through Dallas, Texas.
Lee Harvey Oswald was arrested and accused of killing Kennedy, but before he could stand trial, Oswald himself was shot and killed by nightclub owner Jack Ruby.
The official investigation concluded that Oswald acted alone. However, the assassination has generated conspiracy theories for decades.
Questions have been raised about the number and direction of the shots, Oswald's background, Jack Ruby's motives and whether other individuals or organisations could have been involved.
Over the years, theories have implicated everyone from organised crime and the CIA to foreign governments, although none has been proven to have orchestrated the assassination.
Do you believe Lee Harvey Oswald acted alone? Or do you think there is more to the JFK assassination than the official explanation?
