Sinn Fein leader Gerry Adams has responded to clashes in Belfast between loyalist and republican protesters over Belfast council's decision to restrict the flying of the Union flag.
Mr Adams said there should be a cross-community response. He added:
"But there can be no going back. The tiny minorities who want to cling to the past must be rejected. Sectarianism must be tackled and ended."
Twenty-nine police officers were injured during sectarian riots between republicans and loyalists in east Belfast today.
The union flag will be raised at dawn over Belfast City Hall for the first time since the dispute began last month.
Police were attacked for a third night, with frontline officers reportedly coming under gunfire as new loyalist trouble erupted in Belfast.
