Sinn Féin has stepped up opposition to rulings by the Parades Commission on contentious Orange parades to be staged in Belfast on July 12th.
Party president Gerry Adams warned that the decision to permit, with conditions, marches in the Ardoyne and Crumlin Road areas and along the Whiterock Road had created "an extremely volatile situation".
He said he would not be putting pressure on former republican prisoners released on licence under the Belfast Agreement to act as stewards at counter-protest march flashpoints.
Citing the rearrest of Shankill bomber Seán Kelly following violence at an Orange march in Ardoyne on June 17th, Mr Adams said he understood why no former prisoner would want to risk "reincarceration" by marshalling protesters.
Branding the Orange Order an anti-Catholic organisation, Mr Adams said Orangemen were "insisting on marching through nationalist areas where they are unwelcome This is not simply about a march past Ardoyne shop-fronts, it is a march past three nationalist areas".
He said he understood, supported and appreciated the right of the Orange Order to march. "However, they need to engage in real and meaningful dialogue with local residents in areas where concerns have been raised about their marches. In Derry, such a process of dialogue was embarked upon, and an accommodation was reached.
"Without dialogue no accommodation is possible. Dialogue obviously presents a problem for some Orange leaders. This is not surprising given the history of the order."
Mr Adams said by permitting the Orange Order to march past Ardoyne, the Parades Commission "has created deep anger in north Belfast".
Sinn Féin would now seek a formal review of the decision.
Mr Adams added: "I am also appealing for calm and for peaceful protests against the Parades Commission decisions. Violence on the streets will not help anyone. It will serve the agenda of those opposed to change, and will erode further confidence in the wider political process."
Ulster Unionist leader Sir Reg Empey, who met the Orange Order to discuss contentious parades yesterday, called for a "global solution" to the issue. He said it was up to the order to decide if it should talk to nationalist residents' groups.
"Many people find themselves under severe pressure in different localities. People at interfaces; their lives are turned upside down and there's a whole issue of rights and culture involved in this. We're interested in not seeing issues left simply to local circumstances.
"We believe that instability has been created each summer, and we want a global settlement. In other words, that there's a general understanding right across the community, a consensus into how these issues are going to be specifically dealt with."
Orange grand master Robert Saulters said the policy was not to talk to groups "fronted by IRA/Sinn Féin", but it could change when the order's leadership meets after the marching season in September.
He also denied he had set out last week to criticise Orange Order members who had been involved in local discussions with residents and others in west Belfast and in Derry.
Sinn Féin's Martin McGuinness, seizing on his remarks, said Protestant opinion now accepted that dialogue between marchers and residents was necessary.
He told The Irish Times: "There is a tide of opinion within the Protestant community advising the Orange Order to get sense and to recognise that they should be talking to people."
