A political party linked to the New IRA has distributed leaflets around north Belfast, calling on people to “agitate”.
Saoradh has been in the headlines recently, following the murder of Lyra McKee.
The group denies being the political wing of the New IRA, which has already admitted carrying out the murder of the 29-year-old journalist.
She was shot during disorder in the Creggan area of Londonderry three weeks ago.
Saoradh, which has an office on the Antrim Road, has been distributing leaflets around the north of the city.
They urge people not to “emigrate but to agitate”.
Alliance councillor Nuala McCallister said: “It is a bit provocative in my opinion, the election last week sent the message that people don’t want this kind of radical politics.
“People do not want this in the community, least of all in north Belfast.
“Lyra McKee is from north Belfast, her family live here and it’s really sad to think they might actually see these being put out into our streets.”
Four men were arrested in Londonderry on Thursday under terrorism legislation by police investigating the murder of Lyra McKee.
They remain in custody.
