The 5,000-strong rally involving republican groups on August 9 will mark the 42nd anniversary of the introduction of internment.The three-hour march, organised by the Anti-Internment League will begin in Ardoyne at 6pm before making its way to the city centre and along Royal Avenue.Organisations taking part include the Republican Network for Unity and 32 County Sovereignty Movement.The Parades Commission determination ruled that the march should comply with the adjudication body's code of conduct. Marchers must "behave with due regard for the rights, traditions and feelings of others in the vicinity".No depictions of firearms or uniforms that could be interpreted as that of a proscribed organisation should be displayed during the parade.Several hundred people plan to join protests as part of three groups: Greater Concerned Residents Group Belfast; Concerned Residents Group Shankill Belfast and United Protestant Voice.Organisers of the parade have said the event has been arranged to highlight the "internment" of some dissident republicans facing paramilitary-related charges.
