Families of soldiers killed in the IRA bombing in London's Hyde Park are reportedly taking legal action against a former suspect in the attack.
Relatives of two of the four members of theRoyal Household Cavalry who died in the 1982 blast told The Sun newspaper they wanted "justice" for their loved ones.
Convicted IRA member John Downey was charged four years ago with the murders, which he denied.
The prosecution at the Old Bailey collapsed in 2014.
The case against the Co Donegal man was ended because British government officials mistakenly sent him a letter in 2007, as part of a controversial On The Runs scheme, telling him he was no longer a wanted man.
Now Sarahjane Young, daughter of Lance Corporal Jeffrey Young, who was 19 when he was killed, has filed a civil claim at London's High Court against Mr Downey, The Sun reported.
The car bomb left in South Carriage Drive killed Squadron Quartermaster Corporal Roy Bright, 36, Lieutenant Dennis Daly, 23, Trooper Simon Tipper, 19, and Lance Corporal Young and injured others as they rode through Hyde Park to the changing of the guard.
Seven horses were also killed as the soldiers travelled from their barracks to Buckingham Palace. Another horse, Sefton, survived terrible injuries.
Backing the claim Mark Tipper, an older brother of Trooper Tipper, told The Sun: "If we can get this man before the courts in some way, it will show the British public at least still believes in justice.
"We've been let down again and again by the authorities over the past 35 years and, if I'm honest, at times we've almost given up hope. We just want to get justice for them, no matter how long that takes."
