Loyalist protestors carrying Union flags block the back of the City Hall in Belfast where councillors are debating whether or not to keep the flag flying at City Hall. Currently the flag is flown every day of the year at the building. Nationalist councillors want it removed as they argue that this would create a more equal and neutral environment.
