A memorial service has been held to mark the 50th anniversary of the death of Senator Billy Fox.
The 35-year-old Fine Gael Senator was the only member of the Oireachtas to be murdered during the Troubles.
A wreath laying ceremony took place in the Billy Fox Memorial Park in Derrygoony, Co Monaghan earlier today.
Taoiseach Simon Harris and Minister Heather Humphreys attended the event. President Michael D Higgins was represented by his aide-de-camp, Colonel Stephen Howard.
A church service was held at Christ Church, Aughnamullen, where Billy Fox is buried.
Billy Fox was killed on the night of 11 March 1974.
He had been visiting the family home of his girlfriend Marjorie Coulson near Clones in Co Monaghan, when he interrupted a Provisional IRA raid.
A gang of around a dozen raiders were searching for guns that they had been wrongly informed were being stashed at the property.
The Coulson family was ordered to leave the house, which was burned down.
Billy Fox was shot dead and his body was found in a field the next day.
Mr Fox was an only child, and a farmer who came from a Protestant background in Co Monaghan.
He was elected to Dáil Éireann in 1969 where he served as a Fine Gael TD for Monaghan until 1973.
In the subsequent election he lost his seat but was then elected to the Seanad.
Five members of the Provisional IRA were later convicted in relation to his murder.
