The Parades Commission in Northern Ireland has imposed a number of restrictions on a controversial Orange Order march when it passes a Catholic church in Belfast this weekend.
About 2,000 marchers are to parade past St Patrick's Church and the commission says only hymns are to be played then by the accompanying bands.
It also said that no loyalist supporters are to accompany the parade at this point.
Up to 30,000 people are due to take part in the main parade to Stormont, which marks the centenary of the signing of the Ulster Covenant in 1912.
A planned nationalist protest at the church is to number no more than 150 people.
The Orange Order had offered to play hymns as the march passed St Patrick's Church, but a nationalist residents group had requested that no music be played.
Violence flared outside the church in August when loyalist bands defied a ruling from the commission banning the playing of music.
Seven PSNI officers were injured in the subsequent riots.
