Gerry Adams has said troublemakers should stay away from the Sinn Féin protest in Belfast tomorrow against a British Army homecoming parade for troops who served in Afghhanistan.
The party has also re-routed its march in an attempt to lower tension.
Northern Ireland's Parades Commission welcomed steps taken by both sides to lower tensions ahead of tomorrow's parade.
However there is still potential for trouble, with people coming to support the troops and a protest by the republican group éirigí.
The Sinn Féin President said his party would not allow what he said would be a dignified protest organised by his party to be overshadowed by others.
He said that they may bus people in but we are making it very clear no one is going to piggy-back on what is going to be a very dignified and solemn protest led by families who have suffered grievously at the hands of the British Army.
Mr Adams criticised the British Army for holding the parade but said he saw no reason why the city centre could not be shared in a dignified and peaceful way with others of a different view.
Meanwhile, suspicious devices that were found in Larne and Glenavy in Co Antrim have been declared as elaborate hoaxes.
British Army bomb experts checked out suspicious objects at both locations.
A British Army ceremony in Larne where Royal Irish Regiment soldiers who served in Afghanistan received the freedom of the borough went ahead as planned and was not affected.
However, there was another security alert on the railway line between Larne and Whitehead.
Train services were suspended while the line was checked and a bus substitution service operated between the stations affected.
