Northern Ireland Secretary Hilary Benn has condemned "racist violence" in Belfast in recent days and stressed that it "does not represent Northern Ireland".
Mr Benn said he was "deeply shocked and angered" after hearing from business owners who had been targeted by "rampaging disorder" following anti-immigration protests.
He said he had spoken to First Minister Michelle O'Neill, Deputy First Minister Emma Little-Pengelly, Justice Minister Naomi Long and Chief Constable Jon Boutcher.
He also spoke to representatives of the Islamic centre, as well as police officers and firefighters who had responded to the disorder.
Speaking at a community centre in Belfast, Mr Benn said there was a responsibility on all elected representatives "to call out this racist violence for what it is".
"What we have been witnessing is completely unacceptable. This does not represent Northern Ireland. It doesn't represent the great city of Belfast. This is not what Northern Ireland wants to be known for," he said.
He said: "People are entitled to protest and people are entitled to their political views, but there is no justification whatsoever for engaging in this kind of violence that is targeting particular communities.
"Members of these communities, some of whom I've met today, are frightened. They are afraid. People are afraid to go out of their own houses."

He said this included health workers who are unsure they wanted to stay in the region after the disorder.
Mr Benn called on people to imagine if it was their family business or home and people tried to kick in the door, as had happened on Tuesday night in Belfast.
He said: "What is that about? These are people living in our community. They are part of our community, and you know where we should feel safest? It's at home.
"When people are at home and they don't feel safe, that, I think, reflects very badly on all of us. It should be a cause of shame that this is taking place and my message is: stop."
Six people, ranging in age from 14 to 41, have been arrested following a number of race-related hate crimes and disorder across Belfast on Tuesday.
The incidents in Belfast include an attack on a boy by a group of youths and an attack on a Middle Eastern supermarket on the Falls Road.
Police Service of Northern Ireland (PSNI) Assistant Chief Constable Melanie Jones described a third night of officers dealing with incidents such as assaults, criminal damage and arson in a challenging environment.
The unrest started in Belfast on Saturday following an anti-immigration protest and continued on Monday evening in the south of the city.
It comes amid scenes of disorder in parts of England in recent days.
Four men linked to disorder on Saturday appeared at Belfast Magistrates' Court on Monday.
Later, a 15-year-old boy is due to appear before Belfast Magistrates' Court charged with two counts of riot and possession of a weapon with intent to commit an indictable offence.
Ms Jones said yesterday that officers received a report at around 6.10pm that a shop on the Falls Road had eggs thrown at it and that staff inside were being racially abused by a group of young people.
"A 15-year-old boy was assaulted, and while he received minor facial injuries, I have no doubt this was a terrifying incident for the young victim," she said.
"When police attended, a large group from the local community were outside to defuse the situation. A 14-year-old boy was cautioned for offences such as common assault, disorderly behaviour and criminal damage. We will review the evidence gathered and follow this up in the coming days."
Meanwhile, there was a report of a group of young people wearing masks in the Shankill area.
Ms Jones said officers attended and arrested three boys, two aged 16 and one aged 14, on suspicion of riotous behaviour. They remained in police custody on Wednesday morning.
"We also dealt with a report of a hijacking in the Fingal Street area of west Belfast at around 8.45pm, followed by a report that a car was deliberately driven at a business in the Woodvale Road area, causing damage to the shutters. The suspects made off from the scene," she said.
"Officers dealt with a number of reports of criminal damage to homes and cars in the Enfield Street, Woodvale Road and Rathlin Street.
Three men, aged 26, 28 and 41 years, were arrested in connection to the Rathlin Street report on suspicion of offences including criminal damage and they remain in custody at this time.
"There were also reports of bins set on fire in the Newtownards Road area of east Belfast, which caused some traffic disruption for a period of time as the Northern Ireland Fire and Rescue Service dealt with the fire."
Ms Jones described the scenes in recent days across Belfast as "a disgrace" which "have no place in Northern Ireland".
"We continue to engage with the groups affected by this criminality and hope these arrests show the community that we are taking action," she said.
"Our Public Order Enquiry Team will continue to review footage to attempt to identify those involved, as well as those organising and orchestrating this disorder. As with any investigative process, the Police Service will follow the evidence and present it to the Public Prosecution Service.
"I am appealing to the public directly: do not let these criminals hide in your community. Anyone with any information which can help identify any of these individuals should contact police.
"We have set up a Major Incident Public Portal for people to submit information, images and footage.
"Photos and footage, including CCTV, mobile phone or dash cam footage, can be shared with police through the Major Incident Public Portal at Public Portal (mipp.police.uk)."
Church leaders condemn 'racist, hate-filled' violence
The Presbyterian Church in Ireland has joined wider civic society to condemn the protests and violence in Northern Ireland.
Clerk of the General Assembly and General Secretary of the all-Ireland denomination Reverend Trevor Gribben said racist, hate-filled, wanton violence and destruction "has no place in civilised society".
He said that while lawful protest about a lack of social housing and the underinvestment in jobs and community development in many areas can be legitimate, what had occurred in recent days had been "neither legitimate nor lawful".
"Neither has it in fact been protest," he added.
In a statement, Mr Gribben reiterated an appeal he made last week - to those who are planning further street protests and those encouraging direct counter-protests - to think again.
"This is a time to de-escalate the tension in our community, and not heighten it. Seeking the peace and prosperity of the city sometimes means setting aside our right to protest, or counter-protest, for the common good. This is surely such a time."
On Saturday, Church of Ireland bishops whose dioceses cover Belfast condemned the violence that occurred.
In a joint statement, Bishop George Davison and Bishop David McClay said it was imperative on the church, in every local context, to find ways to welcome the stranger, to care for the refugee, and to extend God's love, kindness, grace and care to everyone.
"This is a time for all of us to work together, pursuing acts of welcome and kindness which are always stronger and more powerful than anything that flows from fear and prejudice," they said.
