More than 100 protesters gathered outside the City Chambers in Glasgow to show solidarity with the unionist cause in Northern Ireland.

Some waved the Union flag and sang the national anthem in protest at Belfast City Council's decision to stop flying the flag over the City Chambers, a move which has provoked disturbances on the streets of Ulster.

Police in Belfast came under attack last night in Newtownabbey, when officers were pelted with petrol bombs and fireworks. It came amid a legal threat by the Democratic Unionist Party over claims the decision to fly the flag on 18 designated days breached the council's equality scheme.

In Carrickfergus, County Antrim, police fired a plastic bullet after being attacked by 100-plus loyalists throwing missiles.
