Extra police and soldiers are expected to be drafted into north Belfast tomorrow in preparation for a controversial loyalist parade through a nationalist area.
Ardoyne residents had objected strongly to an Apprentice Boys march, which takes place at a time when violence in the area has been escalating.
However, the Parades Commission turned down an appeal from Sinn Fein to have the march diverted away from the contentious section of the route.
Tension is high in the district following the eruption of fresh violence last night when security force patrols came under attack in several separate incidents before rival groups of nationalists and loyalists clashed.
Extra police are already patrolling the area in an effort to stem the tide of rising violence but it is expected many more will be drafted into the area tomorrow.
Vicious rioting has broken out in the past after loyalist marchers made their way through the area.
Tension has increased in the area in the run-up to the march despite the revelations that republicans and loyalists have entered high level talks in a bid to end the recent violence.
Sinn Féin's Mr Gerry Kelly held a meeting with the Rev Mervyn Gibson, chairman of the loyalist commission, a group that includes paramilitary representatives.
Sources close to Mr Kelly confirmed the meeting took place in an effort to persuade the UDA to stop attacking Catholic homes.
