Doctors who tried to save the life of President John F Kennedy after he was shot in 1963 said they believed there was ‘more than one shooter’ in interviews that are set to air for the first time.
The medics spoke out in 2013 but the footage was kept under wraps for a decade.
It will feature in new documentary JFK Assassination: What Happened in the Trauma Room?, which airs on Channel 5 on Sunday.
Kennedy was shot during an official visit to Dallas, Texas, on November 22, 1963 and pronounced dead after arriving at the Parkland Memorial Hospital.
Official investigations concluded that he was assassinated by lone gunman Lee Harvey Oswald from a sixth floor window of the Texas School Book Depository.
But numerous books and documentaries have challenged that conclusion in the six decades since the killing.
The seven doctors who spoke out treated Kennedy at Parkland, where he was taken to in his open-top limousine after being shot in the head.
