A small counter protest organised by ‘Causeway Trade Union Council’ also gathered in the same area in opposition to the rally.
They held flags, banners and played music.
NIPSA Northern Ireland Deputy General Secretary, Patrick Mulholland, was part of the counter protest which he said was aimed at sending a message for “unity of the ordinary people”.
He added that the trade union he represents regularly attends demonstrations calling for more social housing and to defend public services that women and children rely on.
“Unfortunately the people who are at this demonstration today, the far right demonstration, are never on the demonstrations which take place to advance those issues,” Mulholland said.
“They are always on the side of division. They are never there to put forward a positive message.”
