Police in east Belfast have used water cannon after coming under attack from about 100 loyalist protestors for the third day in a row.
There are reports that shots were fired, as demonstrators threw bricks and smoke bombs.
The protest was the latest against a decision to limit the number of days the union flag is flown over Belfast City Hall.
