Belfast , Northern Ireland ( CNN ) -- Scores of youths attacked police in Northern Ireland for a second consecutive night Tuesday in an expression of rage over a parade in the Ardoyne area of north Belfast . Nationalist youths threw stones , gasoline bombs , golf balls and fireworks at police attending the Orange Order parade -- held on a date often marked by sectarian violence . After the march passed , the rioters grew in number and ferocity ; police responded with plastic bullets and water cannon . Outbreaks of violence also ignited in East Belfast , Derry and other parts of Northern Ireland . Police appealed for calm on Tuesday . `` Whilst I commend the bravery and leadership of many within the community who worked tirelessly to reduce the disorder and calm tensions -- we need everyone to keep working to build and maintain calm across all local areas , '' Assistant Chief Constable Alistair Finlay said in a statement . He said a number of officers were injured during the disorder . `` We have unfortunately witnessed first hand this evening how violence damages people 's homes and businesses , it sets back relationships and leaves wounds which take time to heal , '' Finlay said . `` It is not representative in any way of the vast majority of people here who want to get on with their lives . '' Tuesday 's incident came a day after at least 22 officers were injured amid similar attacks elsewhere in Belfast . On Monday night , police fired more than 50 plastic bullets and used a water cannon to disperse rioters , who threw more than 40 gasoline bombs , the Police Service of Northern Ireland said . A number of arrests were made , police added , without specifying how many . Monday 's violence was centered in Catholic areas of Belfast ahead of the main day of the Protestant marching season , when loyalists parade through the streets . A spokeswoman said the trouble started late Monday and continued into Tuesday . The most serious disorder was in the Broadway area of west Belfast and involved 100 to 200 people . Police were investigating reports that gunshots were fired during the disturbances . Police said several vehicles were hijacked and set afire in the area , while crowds attacked officers with missiles `` including masonry and petrol bombs . '' At one point , a bus was hijacked and driven toward police lines but crashed a short distance away . Ahead of the march , Assistant Chief Constable Dave Jones had called for community restraint . `` We would appeal for everyone to do everything they can to help ensure all areas are calm and peaceful over the next 48 hours . Violence does not need to be inevitable , '' he said after Monday night 's rioting . In recent years , public disorder has followed the annual parade . The province suffered decades of violence known locally as the Troubles , in which more than 3,500 people were killed before a 1998 peace accord known as the Good Friday Agreement . In each of the last three years , violence organized by people opposed to the peace process has erupted around the parade . The Troubles pitted mostly Catholic republicans , who want the province to become part of the Republic of Ireland , against pro-British loyalists , who are mostly Protestant . This year has been one of the most violent since the Good Friday Agreement .
Fresh violence breaks out at Orange Order parade in North Belfast . At least 22 police officers were injured in clashes on parade , police say . Security forces respond with plastic explosives and a water cannon . This clash has been one of the most violent in Northern Ireland since a peace agreement .
