Wreaths have been laid at the grave of 'Hooded Man' Gerry McKerr in Co Armagh to mark the fiftieth anniversary of the introduction of internment.
Members of Republican Sinn Féin were joined by former internees and relatives at St Colman's Cemetery in Lurgan for a short ceremony yesterday.
A native of Lurgan, Mr McKerr died in 2015 aged 71.
He was one of 14 Catholic men from across the north who claimed they were subjected to state-sanctioned torture when they were interned in 1971.
The techniques they were subjected to included being hooded, made to stand in stress positions, forced to listen to loud static noise and being deprived of sleep, food and water.
In some cases the men were also thrown from helicopters they were told were hundreds of feet in the air despite being just feet from the ground.
More than 1,900 people, mostly nationalist, were interned without trial between 1971-1975.
Mr McKerr was released from prison in the final year of internment and later survived a loyalist murder bid during which he was shot twice.
Just weeks later a bomb was found under his car.
Wreaths were laid on behalf of relatives and Republican Sinn Féin while a short address was delivered by local representative Martin Duffy.
