A prisoners welfare group has launched a campaign to highlight the length of time some republican inmates are spending on remand in jails on both sides of the border.
The Irish Republican Prisoners Welfare Association has put up posters across Ireland claiming that inmates on remand in Maghaberry, Hydebank and Portlaoise, in Co Laois, have amassed over 11,000 days detention between them - the equivalent of 30 years.
The IRPWA currently lists 27 prisoners it represents across Ireland with 15, just over half, currently serving time on remand.
A total of 21 prisoners are held in the north, with the majority detained at the high security Maghaberry Prison in Co Antrim.
IRPWA spokesman Paddy Gallagher said what he called "internment by remand....involves holding republican prisoners for extended periods without the granting of bail".
"This has witnessed republican prisoners being held for a number of years without facing trial and often ends with charges dropped or cases falling apart."
He added that inmates on both sides of the border "have amassed over 11,000 days and counting between them while being denied bail".
And he added: "We have also witnessed a sharp increase in refusal of compassionate bail."
The Department of Justice was contacted.
