Ruthless IRA boss Martin McGuinness apparently helped set up a car bomb that later blew up in the Londonderry city centre, newly recovered video has revealed.
A documentary that was hidden away for nearly 50 years shows how a group of men, including McGuinness, seemingly packed explosives into a Volkswagen on a street in Londonderry, Northern Ireland before the vehicle was driven away.
The video then cuts to the moment a car bomb was detonated on Shipquay Street in 1972.
