Belfast loyalist violence ahead of city council meeting
Police have faced a fourth night of violent protests in east Belfast about the decision to limit the number of days the Union flag is flown over City Hall.
Belfast City Council will meet on Monday evening for the first time since it made the decision.
A demonstration took place near the nationalist Short Strand area on Sunday evening.
Later, bricks, barriers and bottles were thrown at police as hundreds of protesters walked up Castlereagh Street.
