A major new report has warned Brexit could add "fuel to the fire" of paramilitary activity in the North.
The Independent Reporting Commission says the level of violence remains "serious and concerning".
It's increased in the last year, with 3 murders and over 80 punishment-style attacks.
The report says Brexit uncertainty and "references to a hard border between the two jurisdictions on the island of Ireland, is being used by some as a pretext and justification for the continuation of paramilitary structures."
Tim O'Connor is the Irish government's representative on the commission.
He says Britain's departure from the EU and the lack of a power-sharing government at Stormont are two major factors:
"Uncertainties like Brexit become a new fuel adding to that preexisting fire.
The real reality here is that paramilitary activity continues to exist and we need a redoubling of determination to bring it to an end.
We are also saying the single biggest and most positive contributor to ending paramilitarism would be the return of political decision making at Stormont."
